The Grandpa Effect

I don't know what it is about my Dad, but my kids have always had the same reaction to him. It's the craziest thing...I call it the Grandpa Effect. All he has to do is be in the room and they go insane. He doesn't have to talk or interact with them in any way. He can sit on the couch to read a book and the kids start bouncing like someone pumped sugar into their veins. They scream and climb all over him like he's a jungle gym. Poor Dad - I keep trying to tell them he's getting fragile in his old age :p (totally kidding, Dad), but it doesn't matter, they can't control themselves around him. They make him mad sometimes, but secretly, I bet he's loves the extra attention.
