just text her/him

well there was this really cute guy in my class and he knew my brother who was a year younger and he got my number from him( or you could get it from one of their friends)and i didn't have his number and we have only talked a couple of times in person but i was really happy he texted me even though i didn't really like him but now i sorta do and we talk all the time. so just text em even if u barely no them!
