Grandpa: . . .that's very dangerous and you should never do that.
Boy: What if I want to go inside a closet full of spiders?
Grandpa: A closet full of big scary spiders would be very dangerous and you shouldn't do it.
Boy: But what if I take a robot with me?
Grandpa: The robot wouldn't know what to do. That's why you have me. I'll always protect you.
(Me: awwww. . .)
