Is it normal that my grandfather lightly slaps me for no reason?
My Grandfather is 83 and he's a feisty guy.
He raised three highly successful daughters; my three aunts.
He is loving, energetic and crudely funny.
He likes to swear at telemarketers and play
pranks on the family.
Sometimes,when we are all hanging out and talking, and I might
say something stupid or something that seems strange to his old fashioned way thinking, he will slap my legs or arms.
I know it isn't a real hit, but what is it?
Sometimes when he does it I'll playfully ask him, "Hey? What's wrong?" but he never answers.
Is this just an old person thing, or a guy thing or what.
