Birthday cakes

I was supposed to have bought cakes for my colleagues at work for my birthday. I was supposed to have done this at the start of last week, but I forgot. And then I forgot at the start of this week too. On Wednesday, my boss drew me a diagram explaining how to buy cakes, with a deadline of Thursday. On Thursday however, I was too busy. So today my whole team frogmarched me to the cake shop where I finally bought the cakes. I wouldn't have minded except that I was full of lunch at the time and didn't want a cake. So I didn't have one.
