I love my grandma dearly, but she's crazy. Really.
Someday, I will compile a hilarious collection of all the grandma-isms. But for now, here's one.
Grandma: [coming out of the bathroom after her shower] I used the last two towels in there.
Mom: Two towels?
Grandma: Yeah, the last two on the rack, you know, behind the door.
Mom: Why two towels?
Grandma: Because they were the last two.
Mom: Yeah, but why two?
