Heading to the dentist

I think waiting to do something, you don't want to do, time definitely slows down.

I have an hour to wait before my dentist appointment and I think I have looked at the clock every 5 minutes.

You build the whole thing up in your mind to monstrous proportions and even knowing exactly what the dentist is going to do doesn't make this waiting any easier.

All I can be assured of is, in roughly 2hrs time, I will be poorer, sorer and a numb face.
