Most Helpful Girl
Umm I would find the message more weird but I am a little older and social media didn't take off until I was your age soo we talked to people in class and that's just what I'm used to.
In class is nice because then you can feel the chemistry or lack of.
A message could work I would maybe make a joke about how it may be weird but you just wanted the chance to talk to her.
I met my first love in class, I had no idea who he was. He sat across from me ( like facing me). I was actually checking some other guy out when he thought I was looking at him. He rather loudly I might add asked "what are you staring at". I'll tell ya that was embarrassing and awkward but it got us talking and that was the strongest connections I ever shared with someone.
