mom: so, I bought four cases of coke today...

me: four cases?

mom: yeah, it was four cases for eleven dollars.

K : really? cause that's pretty cheap - I bought coke for a dollar a liter last weekend.

mom: yeah, but with the liter bottles you have to go get a glass and ice...

K: yeah, you wouldn't want to waste time doing that.

mom: so, as I was saying, I bought four cases...

me: wait, so, how many cans is that?

mom: I don't know, there's twelve in case...

K: really? because there's twenty four in a case of beer...

mom: so, what? then twelve in a case?

me: well, not eleven...

K: so forty eight cans...sheesh, and I don't even do well with my twelve times tables.

me: twelves? that's easy...eleven's easy, ten is like nothing...

K: no, twelves are tough. Like the eights, god, eight times six, eight times seven...it's the black hole of muliplication!

mom: so I bought four packs of coke today...
