Simply just hold her hand.
I'm in a train compartment with Seamus, Lavender, Parvati and Neville. We still have a good five minutes before departure, but figured we'd just sit down now and hang out. They're all involved in conversation that I chose to skip out on. I wanted to sketch a picture for Ginny to have. She should be coming by the compartment about half way through the trip I believe she said. That should be enough time for a decent picture.
Her timing is perfect. Just as I put the finishing touches on it she walks in. I quickly scoot over to make room for her between Neville and me while all the others greet her.
"Hey Dean," she says smiling. "Hows the trip been so far?"
"Alright, haven't been paying much mind to it."
"Well what have you been doing?" Excellent, I was wondering how I'd give her the picture. She makes it so simple.
"Working on this," I say while handing over the picture. Her eyes light up.
"Oh Dean it's wonderful. You drew this?"
"It's nothing special, it's not like I came up with it myself," I say modestly.
"It's still brilliant though. And you've done it by memory haven't you?"
"Ginny, if I couldn't perfectly draw the Gryffindor symbol by memory I'm a disgrace to the house." She laughs. "Well it's true!"
"Well you certainly aren't a disgrace to your house. It's beautifully done," she says, trying to hand it back to me.
"Keep it. I drew it for you," I tell her, shoving the sketch back towards here.
"Really?" she asks with pink cheeks.
"Oh, no, I'm lying." I say sarcastically.
"Thank you Dean. It'll look wonderful in my room," she smiles brightly.
The others finally draw us into conversation. I wanted to talk to just her more. I'm really beginning to like her. And I'm pretty sure she's returning those feelings. I'll have to keep in touch with her over the summer.
As the conversation goes on I slowly slide my hand towards hers and interlock my fingers with hers, carefully watching her face to see her reaction. She gasps and turns her head to look at me. I smile shyly at her and she returns it, squeezing my hand gently before returning her attention to the conversation with a grin.
Our hands are clasped right up until she needs to retrieve her trunk and leave the train. Both of us make promises to write.
