A person who takes forever to do anything, and if you talk to them, they might as well be deaf and dumb.
He took 45 minutes to walk from the kitchen to the living room. I'm not even mad, I'm just confused.
I asked him a question, and he just stared at me like I was speaking a different language.
He couldn't even pick up the phone when I called him. He just sat there like a statue.
