while dragonlette may (is probably) right about what her friends mean by "lucky" it may be more complicated (and a bit more reasonable) than that. I think that you are lucky, Dragonlette, not because that is what your dp does with some of his time, not at work; but because you have a house with 2 adults and 1.5 full time WOH jobs. that is an enviable position to be in because there is a ton of stuff that can be done nicely, calmly, in daylight with no pressure.
Like the bedtime thing. Presumably you do that to spend time with the dcs after being out at work all day, and he gets on with the dinner because straight after bedtime you will both be hungry. that sounds like bliss to me, I would very happily be either you or the cook in that scenario, just for the pleasure of having a time slot to do everything in and only doing one thing at once. My least favourite time of the day usually is 8.30 pm when I shamble exhausted into the kitchen which I last saw at 7.30 am and try to think what on earth I can make to eat and then open the fridge and realise I can't even think about cooking till i have found out what is making that awful smell. There are weeks where I cry literally every day with hunger or tiredness or both. Right now I can't face it and eat something from a packet on the train at 6.30, which is just making me fatter and fatter so I have draw a line under it and get back to trying to be sensible with food, which basically means being hungry most of the time.
I don't mean "lucky" in a snide way though. I mean it admiringly because you must have done a ton of stuff right to be in that position and you have made good decisions and clever arrangements.
One of the saddest things to me, right now, which makes me feel so unsupported, is that no one thinks about when i might fit some meals in or does anything to help me with them. when I lived at home as a child it drove me nuts that my mother was obsessed with meals and every arrangement to do anything at all involved as a priority arranging what that would mean to meals. Now I wish someone would make me something to eat sometimes
