I was due to catch a flight at 11am from Heathrow to Shannon, Ireland for a wedding. My friends and I were to go straight from the airport to the wedding ceremony that Saturday. Having travelled repeatedly out of Heathrow, I knew exactly when to leave my flat to avoid sitting around Heathrow watching the clock and idiotic travellers shop at an airport. I woke up expecting the day to be relatively calm and peaceful. It took me two hours to experience enough stress and angry thoughts to send most people onto a therapists' couch (or into a mental institution).
