I do... almost every chance I get.
He hates it. LOL
If he is coming out of a room and I'm right there where I can hide and sneak up on him, I'll do it.
I do it to my dog, too. My dog likes to follow me so if she's eating and I'm in another room, I'll hide and see if she can find me. It's even better if I can scare her.
I think I have a problem. Haha.
I'm pretty sure my future kids are going to hate me.
