So I met a girl today who was with/is friends with a girl I'm pretty sure likes me. Well I kept talking with this first girl and she would laugh at almost if not all of the jokes I would make and it really wasn't that hard at all to get her to laugh, but sometimes it seemed like it was a polite laugh or that kind of laugh where you're not sure what what to do so you sorta laugh, but it happened a lot and wasn't a little snicker and was usually more than that so I don't know. Oh and we don't go to the same school and met at a festival thing and when I had to go I also turned around and called out to her that she should join this volunteer thing that was helping a lot with the fest and she looked kinda surprised and said ok. Thoughts on whether she likes me or not? And also how her friend liking me already would affect things?
