Morning MoreLegs. You rant away as much as you please. He does indeed behave like the most selfish of teenagers and, as you say, she is no better. It is all what he wants all down the line and everyone else - you, DC, DFIL - should just accommodate him.
I don't think you're weird to wonder what they're getting up to with the inflatable willy. But it's hardly material for passionate love scenes. "Wait please darling, while I pump up the tackle," is not 'Casablanca', is it? More 'Carry On', really. And what happens if the deflator (or whatever you call it) fails to work...Oh what a trip to A&E that would be...
A rescue dog sounds a super idea. Sadly, I suspect there's going to be quite a few pets available in the next few months. My cats are wonderful company and helped DS in particular so much in lockdown when he couldn't go to school and see his friends. When he was holed up in his room for online lessons on the laptop he usually had one or two cats sitting either beside or on him while he worked. Sometimes they'd appear on camera which livened up lessons no end.
What sort of dog would you like? I have very fond memories of a very friendly poodle-cross type who used to visit (this was in the days when dogs seemed to be more free-range) and play with me in the garden when I was a child. She was adorable.
Have you managed to get to the hairdresser yet? I went early today and no longer resemble Catweazle's granny.
Have a lovely day. Hope you have sunshine where you are. Take care.
