2 weeks I met a girl while I was at the mall I left my guitar in my teacher’s class but at 7:00 I went back to get it (I had to go home) and when I did I walked in on my teacher with a girl my age he asked me to take a picture of them so I did but while I did I felt like I liked her and her accent and the way she was talking was so down to earth and last week I went and left my guitar there and went to pick it up at 7 when I did she was there and she helped me get my guitar and winked at me I didn’t know what to do so i smiled thanked her winked back and left. then this week my teacher told me that she asked about my name and said i was a nice guy. so i am thinking to give her my number or something but there is this other girl i really like and after meeting this girl i am confused if you read my other questions you might know but i have a problem as always i like both and they are both great people that have been very good but the girl i already like who also might like me i have been her friend for to long and i know more about her but as i said she ma like me i am not sure plz help but i am confused about who i should like not if they like me
