A/N: Hello, peoples! It's great to be writing again. I had a minor case of writer's block after I stopped with The Jungle Movie, but now I'm cured. ^_^ Anyway, this plot was sort of a copy from one of my Pokemon fanfics that were never posted here (though it's not EXACTLY like it). Well then, let's go!

Disclaimer: I don't own Hey Arnold. As usual. Now leave me alone before I throw a stick.

"Forgetting is a Dangerous Thing"

{though I don't luv mark anymore :P}

Arnold stomped down the deserted sidewalk to his boardinghouse. He was covered in blue paint from the events at school. When he reached his steps, he went up them and tried his best to get up to the bathroom without being seen. But he couldn't make it in time.

"Hey, Shortman! Why are you all covered in paint?" his grandpa asked, coming out of the kitchen. Arnold rolled his eyes from his spot on the stairs. "Helga poured it on me today during art class," he explained. "Just another one of her pranks." Phil laughed.

"I still say she likes you, Arnold. But, hey. That's just my opinion. Now go upstairs and get cleaned up," he said as Arnold walked the rest of the way upstairs. He walked into the bathroom and began to get undressed from his blue-stained clothing. Turning on the water, he turned the knob to the left, so that it would be warm. He stepped under the running water and felt his hair fall onto his shoulders with the weight of the water on it.

It was already the start of June, he thought. It was amazing how fast the school year had been going. There was only two-and-a-half more weeks left and then it was summer vacation. And naturally, Arnold and everyone else couldn't wait. Him and grandpa were planning to go to the beach again (he was hoping he wouldn't run into Summer) and then to the Dinoland that was there. It was supposed to be bigger than the one there.

Then his thoughts went to events of that day. Everything had been fine until the last period: art class. Mr. Simmons had assigned them to paint pictures of something in the classroom. Arnold had decided on painting the window and the trees outside of it. It was only five minutes before the bell was to ring that Helga decided to be stupid. She stood up, saying she was going to wash off her brush in the sink at the back of the room, and as she walked past Arnold's desk, she purposely knocked his blue paint can off the desk and all over him.

'Oh, I'm so sorry, Arnold! How clumsy of me!' she had said in a fake sympathetic voice. She laughed and so did everyone else with the exception of Phoebe and Gerald.

Glaring at her, he stood up and looked her in the eyes. 'You know what, Helga? I'm really just sick of you and your immature little pranks! You walk around acting like you're big and tough, playing pranks on everyone, but really, you're nothing. I thought there was at least some sense in you, but I guess I was wrong. You're nothing.' He said to her. There was a chorus of gasps from everyone and that was when the bell rang. Instead of following everyone, Helga stood there, dumbfounded. Arnold had already left school with Gerald by the time Helga left the classroom.

Arnold walked home; still furious with what had happened. Normally, it would have worn off by this time, but Helga had pushed him off the edge. He thought it was just letting out that build up of hot anger that he kept in all those years.

Arnold looked down at the water at the bottom of the shower. It was all a dark blue from the paint. After getting it all out of his hair, he turned off the water and stepped out. Wrapping a towel around himself, he dried off his hair with another towel and walked down the hall and up to his room.

There, he got dressed and brushed his hair up. He walked up to the roof of the boardinghouse and looked around. The sun was just beginning to set. He noticed his friends walking around, but didn't say anything to them. He didn't feel like doing anything. That was when he saw Helga walk past.

She looked up and met his gaze. Her face was emotionless and it stayed that way the whole time their eyes were locked. But then she turned it into a scowl and yelled up at him, "Hey, Arnold! Weren't you ever told to wash your ears?" She laughed as he noticed that there was still paint in his ear. He gritted his teeth, walked inside his room, and tried to get the paint out of his ear.

His anger at Helga begun to go down before what just happened. Wiping off the last of the paint, he stood in the middle of his room, hot with anger. He had his fists clenched tight and just stood there for some time, not moving. Finally, he spoke in a whisper.

"I wish that I could just forget Helga. I wish that any trace of Helga could be erased from my memory and be gone forever. I wish that I would never see Helga G. Pataki ever again for as long as I live," he said in a very harsh whisper. Making that wish seemed to do the trick, because after that he seemed to calm down and go about the rest of the day in a better mood.

For the remainder of the day, he didn't think about Helga at all. He hardly even thought about the incident at school. Actually, he didn't think about anything that would make him upset (so, no, he didn't think about Lila). And to his grandfather, it seemed a bit strange that Arnold had come home in a bad mood, and then walk around in a better mood as if none of it had ever happened.

Arnold himself almost thought that the wish had come true, but he as he was crawling into bed, he thought about Helga. Maybe I was just a little too upset about everything today, he thought. But she just makes me so mad sometimes and I guess I just snapped that time. But tomorrow will be right back to normal and things will be the same as it was before today.

And before he knew it, he fell into a deep and peaceful sleep.

A/N: -sings- I got some skeletons in my closet and I don't know if no one knows it. So before they thrown me inside of coffin and closet, I'm gonna expose it.  Oh! Sorry. Listening to Eminem. Anyway, what do you think so far? Please let me know! Flames are welcome too, but not from people who don't like Hey Arnold who are just going to say how gay the show is. I get that a lot, and it's sad. So if you don't like Hey Arnold, why are you here? Go away or I WILL throw a stick.
