So I met cute girl in my high school, and we're talking basicly everyday at breaks. Problem is I can't into kino escalation I just don't know how do I do this properly. I have no problem with talking about things, but ye, can't into physical contact. We met at school's basement where students can sit and spend free time so there are other students aswell, and problem is she is coming and just sit next to me and we are talking (cus I'm first there) or I come as a second and just say hi cus she see me. Wanted to sneak up and say "boo" while holding her shoulders but she is sitting in such places that I cant do that. When we are talking I have no problem with gazing at her eyes 24/7 but I dunno it seems weird to just grab her hand and hold it (especially if i have never done this before).

Should I start to hug her or something while coming there? And if yes still do it while she is seating?

In conversation I wanted give a shot to trick when I give her high five hold my hand a bit longer and split my fingers and see if she grabs my hand. Good method?

Would like to know some new "methods" for having opportunity to touch her while having a conversation, something like hand size comparison (dunno if its good cus I have small hands and she might have bigger :D) or something
