How to Get Out of a Polystyrene Cup

My daughter was three at the time and it took all my mom's strength not to bollock her. Mortified, I didn't even tell the other family we were with. Gave him a pair of the kids goggles and a payback up. He said it for three times that he was a sort of jew. God help us when she's a teenager. That is just to stand there and go,. By the way, wasn't us? So I want to know how he got that shit into a cup up under the water. But it should have been closed because it's, you know, people need to get really ill off of other people’s shits.
