Poop....Such a Distinct Smell

My two year old daughter is just about potty trained. We were at the grocery store, and she told me she had to go poopy. I asked if she could wait just a few minutes, and she said she could (mistake #1: Never trust a two-year-old's judgement on time). Once we got home I had forgotten about her having to go, and I began to put the groceries away. The next thing I knew she was running, with her pants around her ankles, screaming "I gotta go poopy!" I could tell she had pooped, but I couldn't seem to find it anywhere. I just assumed she hadn't really gone yet, so I stuck her on the toilet and cleaned her up. I went back to the kitchen and finished putting the groceries away. I still smelled pooped. I looked everywhere and couldn't find it. I figured it was just lingering from before, but it wouldn't go away. Several more minutes went by and the smell was as strong as ever. I was going crazy trying to find the source of the mysterious poop smell. Finally, my three-year-old son came into the kitchen and said, "Mommy why is there poop on the top of your shoe?" I looked down, and sure enough there was a decently large piece of poop just sitting on the top of my shoe. Ah, the joys of motherhood.
