She's so funny

It's Tuesday and I was thinking about earlier this summer when I had funny saying Tuesday. Last night Faith was sitting on the toilet and she likes to talk on the toilet. I asked what she was doing and she continued on to tell me she was peeing however then she continued to tell me what other people do sometimes. "Mommy, sometimes people poop on the potty. Other times they fart. That is a funny sound mommy." How can someone keep a straight face with that little cute smile looking at you talking about farts? She has started excusing herself when she farts too. Good manners start at home right?
