My elderly neighbour (in his 70s) always had a long standing duty to take his even more elderly mum (90s) out every bank holiday Monday to the Norfolk coast. She always moaned about the traffic on the way.
I said to the neighbour "Why do you have to take her on a bank holiday? You're both long retired, you can go whatever day you want. It'll be quiet on any given Wednesday".
He said she wouldn't accept such a suggestion, it just wasn't traditional since they'd always done a bank holiday run to the coast. Silly, stubborn old beggar.
