My husband often has to work away from home at short notice, doesn't recieve any extra payment for this. The assumption seems to be that he will use his own car to park at the airport while away, but our cars are shared equally (in actual fact I bought them both), and last time, mine broke down hence I had to do without a car for nearly a week. A minor thing perhaps but it also means I have to do without him being around at short notice. We run a rental property business togethhave some rental properties together, on top of our jobs, and this means I have been out of pocket in the past because I've had to buy new replacements items as an emergency when if he had been around for the weekend, he could have fixed them. It would be the same if anything broke in the house while he was away, I would be out of pocket paying to get it fixed. No DCs.
I've also met his work colleagues socially, although very infrequently, and they have never once asked me what I do for a living. I find it a bit odd, as surely its a normal conversation opener?
