newbie here who needs help. posted this under the flirt section but i think it'd be more appropriate here. so i walked into class late (1st day) and grabbed a random seat. this girl sitting beside me (never met or spoken to her before) just out of nowhere offered to send me her notes. also i noticed during lesson she did the occasional glance over and then she smiled when i looked at her. are these ioi's or simply just friendly gestures? also what kind of approach best fits this context? i replied her email with somethin like 'thanks i owe u one, hit me up if u wanna do a study group', bad line?
advice is appreciated thnx
