"Stop playing your pee pee like a guitar."

I'm noticing that many of my quotes begin with "stop" or "don't" and I'm thinking that I might want to rephrase how I begin my sentences, although many of these statements are spur of the moment utterances that fly out of my mouth without much thought. I mean really, what do you say to your 3 year old who is taking a bath and suddenly starts singing "neow, neow" and playing guitar without a guitar? I ignored it at first, but then he tried to get my attention with the direct, "Mommy look at me!" I suppose I could have said something like, "Let's not use our penises as guitars, sweetie." Or, "That's cool buddy, now put your 'guitar' away and clean it," for a positive spin. I have to admit, it was actually funny, but I could also imagine him taking his little show on the road for laughs so I kinda wanted to keep things on the down low. After I said what I said he tried to explain his actions with, "But I'm rock band!" To which I responded "Okay, song's over." And so it ended.
