The young lady (for lack of a better name) behaved disgustingly, to say the least. I am sure we have all had urgent calls of nature, but that is unnecessary. I will always remember the time we arrived in the UK on a visit, had to walk with our suitcase out to the car hire (it was chucking it down and there wasn't a cab in sight, the bus was nowhere to be seen either so we decided to walk - it couldn't be far...) and my young daughter of eight at the time started to complain she needed a toilet, of course, this set me to thinking along these lines...after staggering along for some time, we came to a weeping willow sort of tree on the side of the road, plunked our suitcases beside my long-suffering husband, and ducked in unison under the tree! He looked quite ridiculous in the pouring rain, with three suitcases and nobody else in sight!
