Conversations again...

Ewan: Mommy, why does the rabbit drink water all the time?

Me: Because he gets thirsty.

Ewan: But, why?

Me: Just like us, his body needs lots of water.

Ewan: Yeah, just like our body needs milk and root beer.

Me: (saying) Our bodies don't need root beer, but they do need milk. (Thinking: Yes, Ewan, fizzy brown drinks...my body needs them, but it ain't root beer.)

And this is actually funny only because he's had root beer twice in his entire life.
