she sits at another desk and apparently the people on that desk had been having some kind of discussion on how old they looked etc.

They asked the girl sat next to me, and then me. I hadn't been listening to them and I did the standard thing with women whereby you knock 3-5 years off of the age you think they are so they can be happy about themselves.

So I sized her up and replied 50.

she was actually 39. Enemy for life much?
