hey so i found out about this really cute girl through a couple of mutual friends and decided to randomly add her to see where it goes. before she accepted my friend request she messaged me and asked if she knew me. i told her maybe, and that she looked really familiar. then asked if shes been to this place we occasionally throw parties at. about an hour later she added me but never responded. i wanna start a conversation with her, but i'm having trouble thinking of a good way. any ideas?
