They asked me what had happened and I said 'I'm really sorry, I didn't buy a parking ticket' and they said 'We hadn't even noticed that!', they said 'Do you realise where you had parked?' and I said 'Well no, I have no idea' and they said 'Well actually you parked into the entrance to a car park and as a result nobody could get out of the car park because you were parked in the entrance'. So I wanted to laugh and cry at the same time then. It was very embarrassing: I hadn't seen the sign, I hadn't noticed the car park which was rather silly. Erm, but now my friends think it is really funny when I tell them the story. I also think it's funny but it was an expensive mistake!
