I've given this a lot of thought. I reckon she was on the teams call and her dog does a shit, she goes to pick the dog shit up and the bag splits. She's got dog shit on her hands. It's grim and we've all been there. Luckily a babbling brook of a river is just up past that bench so spying an opportunity she dips her fingers into the water give them a bit of a clean. That's when the dog pushes her in.
