The Things Kids Say

So this boy in my class comes up to me and says: (The boy's name is Alfonso)

Alf: Mrs. Taylor? Do you like my shirt? My ex-brother gave it to me.

Me: Hmmm...How is he your ex-brother?

Alf: Well... My sister has a lot of boyfriends, like 100 of them. He is not her boyfriend anymore!

Me: (chuckle) oh yeah? Well it's a nice shirt.
