I've been in work for about 45 mins and already I've had 6 people asking me if I had a nice bank holiday.
It's bad enough when you've had a holiday and you have to replay those stories over and over. Having said that I also accept that I'm one of those people who feel socially bound to ask if people had a good time to. Personally I think any human interaction before 7am should be banned in the office :)
