When Jose secretly poops on the floor. Only to then have my son unknowingly step on it and walk around the living room carpet for awhile. Then when he notices the poopy, smeared carpet, he tries to scrape the poop off his shoe onto the rocking chair leg. When that doesn't work, he decides to walk through the entire house with the poop on his shoe, only to nonchalantly tell me, "I stepped in poop."
Yeah, that's not awesome.
