You have to be straight forward with guys mainly because some don't get the hints or just don't like being hinted. For example I like to be told directly no friends no family I like them to tell me. It also gets rid of all confusion if you tell them.
You need to be very VERY clear about the fact that most of us boys don't think that small hints or body gestures mean anything (the dummies we are). On the other hand, some boys are smart and notice every little thing that you do. So if the boy you mean is very smart and notices things that other people don't, just a small pastry won't do, you'll have to do better than that. For example: Be nice to him, do the things that the gentleman rules say and maybe take him out to play mini golf or something. Don't take him to the movies for thy can't speak there.
the way 2 our hearts is good food... feed him something good! then tell him you heard the way 2 a mans heart was through food... if he doesnt get the hint...look him in the eyes, and ask him the way in2 HIS heart straight up. show him your intrested in him. If he doesnt get that hint...look 4 a new guy with an I.Q. over 75.... bouna fortuna
