OK, SO this is my little sisters problem, she asked me for help but honestly i couldn't decide! in school, this guy from class that she's not a close friend with started to flirt with her from facebook, than by text messages. But my sister is kinda worried because it seems like he is a bit 'too' interested so she wonders if she should take him seriously or are they just joking with his buddies??? what do you think? I never had experienced such a joke but it felt a bit too flirty to me for the first 2 days when I read the messages...*they are high school seniors
