Youngest son stays with his aunt during the week while I work. She is his schoolteacher, so it works out in more ways than one.
I pick him up from school on Thursday, he has Friday, Saturday and Sunday off, and I take him back Sunday on my way to work.
I will also pick up any needful things for Sis's house while he is there. He will occasionally want something different, and Sis will ask him how he proposes to pay for it.
"That's easy" he replies, "First Bank of Dad!"
Sigh. I think I need a bail-out.
Unfortunately I'm not "too big to fail" so I most likely wouldn't qualify.
