A wee-wee

A conversation I had with Lex the other day. Lex: Mom, I want to do a wee-wee. Me: A what?? Lex: A wee-wee. Me: Use it in a sentence. Lex: I want to do a wee-wee. Me: Um, that's not exactly helping me. Say it slower. Lex: A weee-weee. Me:(trying not to laugh) Sorry, bud, I'm not getting it. Lex: On my bike! I want to do a wee-wee on my bike. Me: A wheely!!! Lex: Yes, that's what I said!
