His vest.
Lisa and Nelson were walking home from school. It was a rainy day and the wind was blowing very hard. Nelson didn't really mind it though. However, he couldn't help but notice Lisa shivering.
"Lisa, are you okay?" He asked.
"I'm fine." She said as she continued to caress her bare shoulders.
"Here." Nelson took off the blue vest he always wore and put it around Lisa. "There. Is it warm?"
Lisa's cheeks turned scarlet as she embraced the vest. "It is. Thank you."
They got to Lisa's house and he kissed her good-bye.
"Nelson, if it's not too much trouble, do you think I could keep the vest until tomorrow?" She asked.
"Sure." Nelson said. Then he went home. Lisa went to the living room and sat on the couch where she embraced the warmth of the vest. Then she heard the front door open.
"Lisa! We're back from Krusty burger!" Homer's voice shouted.
"Oh no!" Lisa thought. "I can't let them see the vest." Lisa quickly took off the vest and put it underneath the cushion she was sitting on. She sat back on it just as her family came into the living room.
"Ahh that was some good meat!" Homer said.
"We brought you a veggie burger sweetie!" Marge chirped
"Just leave it in the fridge. I'll get to it later." Lisa said.
Bart approached the couch. "Hey Lisa! Move your fatass out of my seat."
"No way!" Lisa said.
"You know I always sit on that spot now move it!"
"No!" Lisa was worried. She didn't want Bart to find out she was dating Nelson. Then Bart said something that shocked Lisa.
"Mom! Lisa won't get out of my favorite seat because she think's hiding her boyfriend's vest under there."
"Wait a minute! You knew?" Lisa asked.
"Of course he knows! We all do!" Homer said.
Lisa blushed deeply. "B-B-But H-How?"
"Get real! You think we can't hear you and Nelson talking about how much you love each other or you talking about him to yourself or this!" Bart said as he pulled up Nelson's vest from under Lisa. Embarrassed, Lisa quickly snatched the vest away from Bart and held it behind her back.
"Oh sweetie!" Marge said. "It's nothing to be embarrassed about. I think you and Nelson make a cute couple!"
That comment just made Lisa blush deeper.
"Haha! Lisa's face is as red as a beet!" All the family, including Maggie started laughing while poor Lisa tried curling up in an imaginary turtle shell.
"Someone kill me."
After an evening of awkwardness, Lisa went to bed with the vest. She put at her pillow and laid her head next to it.
"So my family knows." She thought. "Well on the bright side, at least this means I don't have to hide Nelson from them. I can't wait to see him tomorrow." She fell asleep using the vest as a pillow.
