This is kind of a funny story. I was in Toronto and had a layover between flights. I’d arrived at about 6 p. m. and my flight out wasn’t until about 8:30. Well, my flight was delayed. It got really crowded at the departure gate. I was getting tired and there were so many people around. I hate crowds, so I went to sit away from the departure gate to escape the crowds. I was reading my newspaper, feeling drowsy. And then... the next thing I know, I wake up and there’s no one around! The crowd is gone. I had fallen asleep and missed my flight. They must have made lots of announcements and I missed them all. Boy, did I feel stupid? I had to stay in Toronto overnight and catch a flight out the next morning.
