"What Are Computers, MistyCat?"
This question was asked by my little sister. (I replaced my name with my screen name as to not reveal my identity.)
I responded, "Devices that we can type, play games, do homework, listen to music, and share stuff on. They can also be used to annoy the s*** out of old people."
I didn't actually swear, though, so please don't judge. See also Computers.
