How to hide your crush from others and have your crush comfortable around you

#1: don,t tell anyone! some how... when you confide in friends, they seem to spill the beans on you. don,t let it happen to you.
#2: if you ever are in a situation where you and your crush have to do something for a school project... be calm and DON,T act strange and flirt with him too much... it freaks them out. (words spoken from my bro.)then try and talk to them...that isn,t hard is it? ask some questions (not to personal)and wait for an answer.
#3: the crush will start to feel more comfortable around you... then you will have more of a chance of being around them and learning some of their secrets and most of all... just being friends, then the telling of the crush may come later.
