Revenge in the heat of the moment can be a bit sad

Yesterday H was admitted to hospital in Reading after falling off his bike and taking a very severe knock to his head. His mother and I were with him all evening and went back to his house to sleep at 1.30am. I parked in the entry to a parking area behind the house, leaving just enough room for cars to get out. One customer found the task infuriating, and left a note under the windscreen ('thanks for ruining my life, twat' or some such) and a smashed side window. By the afternoon a friendly Lithuanian from Autoglass had fixed it in the hospital car park for a £60 excess, and we were firmly back on the moral high ground.
Twats. It takes one to know one.
