It's my birthday today. At lunchtime I'm sitting with my (new) colleagues having lunch. Someone says 'thanks for the cakes.' I reply, 'no problem, last birthday I'll be celebrating ... It's the big one next year.' She replies, 'oh no! The big 5-0!' 'Er no! 40!!!' Everyone else creases up laughing. I want to punch her! She digs an even deeper hole by saying that because she's 50'she just assumes everyone else is the same age as her etc etc. Great stuff - thanks & happy birthday me!
