I've had guys buy me drinks or order me drinks and I know its flirtatious but what about this guy who offers you a sip of his drink? For arguments sake I know he didn't slip anything in...I trust him and have known him a long time.At the last three parties we have been at he has offfered me his drink or a sip of his...is this flirting or more intimate than if he had brought me my own drink? I'm trying to figure out if he might like me.Also, so u get a better idea he is always on my side of the room or coming to work in my area, makes up excuses of things to talk to me about, has brushed my hand with his when i passed him something, he remebers little things we spoke about a year ago....but at the same time, he hasn't asked me out or anything.Is he shy?Is he just friendly?
