I suppose I am lucky, because before I became a psych nurse, I was a nerd for a living. Building them, mending them, selling them, and then programming them.
But the worst thing is when the pastor of the church knocks on the door at midnight, and asks if you can urgently sort it out for him as his sermon notes are on there for the following day. Needless to say I went (dressed in my pyjamas - england's cold) and spent a couple of hours repairing the mess.
