There's a guy at my church (Alex) who is good friends with our Youth teacher's daughter (Katie). My sister and our friend who is also in Youth (Amy) say Alex likes me, but I'm not sure. They say he smiled when he says my name, act differently around me, and once asked my sister if my best friend (Patrick) and I were dating then said "good" when he told him no. Another time I was talking about how we have to wear our hair to cheer competitions and Katie says, "You really wanna date a girl who's high maintenance?" Does this mean he likes me? Or am I just crazy? Thanks!
