So there's this girl in my college class(strong HB 9, though taller than me so a bit intimidating) that I completely forgot was in that class but then recently remembered was in that class after I went for the 2nd time the whole semester(I Pretty much stopped going to the class after the 1st day of class because it's A) really easy B)it's during times for my intramurals practice). Anyways, she was in one of my classes last year and the 1st day of this class I opened her and her friend, commenting how she was in my class last year etc, but that died down quick when prof started up. Haven't seen her since and I actually forgot her name. I was wondering if I should cold open her and her friend again (since I'm gonna start going to class now I remember she is in it haha) or open her like I've "known her/them for a while". I actually have a genuine interest in talking to her (concerning law school and she is the only other person I "know" who is going to law school like I will be and would like her perspective on it) and wondering if I should open with something along those lines.
