People who don't know how to hang up the phone on someone

At first I thought you meant hang up the phone on someone when you're having an argument or something....those people are weak too, the ones who hang up on someone like a child.

My grandpa never says goodbye or anything, you just hear a click and he's gone

I'm sorry, can you start this thread later?

I always go like this: "Bah-bah."

It's not as satisfying as it was in the 90's. Now I have to say "Click!" and hit the red button.
