What's for Dinner?

I have been asked this question at breakfast before now or at the latest as a hungry boy gets in from school or college. Hubby used to try and ask but I banned him, I think because it reminded me of a pleasant but socially challenged bloke that I worked with when I first left school. He would phone his mum ten minutes before he left work every evening and ask this very question.....ugh!
The thing is, that now I have a pescetarian, with a pescetarian girlfriend and a son not eating red meat, also with a pescetarian girlfriend, the answer to this question is a difficult one.
Number 3 pointed out last week that he, in fact, still likes red meat and misses the old days ( 2015), when he got Toad in the Hole, Spag Bol, with mince, not Quorn or a roast dinner. Oh the guilt.
Hubby had been pointing this out since February to be fair but I had tried to convince him and myself that avoiding red meat was healthy. Anyway, Tuesday saw sausage and mash back on the table but only 3 of us to eat it.
This got me thinking about the many things we stress over when our children are little, only to find them obsolete once they've grown. I prided myself on family meal times, all at the table, all eating the same food, none of this cooking 5 different dinners in my house... oh the irony! The same goes for bed time, the bath, story, sleep routine a well oiled machine for many years, only to be overtaken by teenagers who stay up longer than us. The meticulous teeth cleaning, forgotten at every sleepover. No sweets before meals, ignored as soon as they are able to go out without you. The list is probably endless. We can only hope that some of it got through and some of it did them good. Just wish I could of told that young mum of three little boys not to stress too much. I doubt she'd have listened, much like this older mum of three young men who should probably just cook what she wants for dinner.  EJ
