DD1 had invited 6 girls over for her 9th birthday, and we had taken them for a run around on the local beach. We also had DD2 with us, so DH and I each took a car with 4 girls each. I was a Brownie leader at the time, so well used to wrangling large groups of girls, in fact most of the girls were in my pack. When we got back from the beach, DH took me to one side and whispered urgently "I think one of the girls has shat themselves!"
I spotted one girl hovering against the wall as the others ran around the garden manically, and as I approached, I could smell the problem immediately. I whisked her away and ushered her into the bathroom to have a shower, dug out some clean clothes, rinsed her own clothes and chucked them in the wash.
Whispers were beginning amongst the rest of the girls about what had happened, so I announced "Lucy accidentally got some dog poo on her at the beach, so she's just washing it off", and happily, the girls all accepted my explanation.
I called her Mum and told her what had happened, but that she was fine, and her Mum replied "Not again! I've told her she should use the toilet as soon as she needs to, but she has this habit of hanging on till the last second, and sometimes leaves it too late!" I was a bit surprised, given that she was 9, but it was not the end of the world...
Until DH went to get in his car to go to work the next morning, and as soon as he opened the door he was assaulted by the most god-awful smell. It turned out that Lucy had not only shat herself, but had managed to wipe it on the seat she was sitting on, ground some into the carpet on the floor, and must have had some on her hands, as she'd attempted to wipe it off onto the back of the driver's seat. DH had to get to work, so we ended up giving it all a quick wipe with antibacterial wipes, then spraying the lot with disinfectant spray and Neutradol, then chucking a couple of old towels over the worst affected areas until we could deal with it properly when he got home from work.
Needless to say, DH drove to work with all the windows down!
