I am very patient, comes from years of experience working with complete morons, usually managers/directors. Done loads of remote support which is the most difficult kind.
In the last couple of weeks I visited a friend of Mrs Tel to sort out a few laptop probs - her son who has some kind of problem (no idea what) pounced on me and we had a long session ripping music for his ipod and generally internet stuff - firend remarked on how patient I was.
It's not something I think about, it's just become part of my working nature.
Also going fishing for many years helps with patience.
