Generally not. But then again, I generally dont engage them either. My wife does all the shopping & other than 7-11, I try not to do to stores.
Im relatively friendly with people at my kids games.
I generally find that people suck. They either talk to you in order to brag about how great their kids are or how good they are, or they want something from you.
Most times, I dont really care what they have to say. Have a nice day. Do they really mean it or care if I do? Probably not.
