A few days ago I was standing around reading and I saw a girl I recognized from awhile ago but I never knew her back then so I said hi and she came up and she was asking me some stuff being all flirty and then she says " wow you look different,here let me give you my number" and she writes her number on my hand and tells me to call her. I really don't like this girl much but I could use another f-buddy around here so I was wondering what the best thing to do is?
