My MiL is notorious for giving “useful” gifts - An ashtray and a can of lager for my DS ( who doesn’t smoke but I guess he drank the lager), a big ball of elastic bands she’d collected which had been discarded by the postman for one of the DC; last year’s diary for me ( “you can just change the day and it will be ok, and I’ve only written on a few of the pages”) ...you get the drift. At least we have a laugh about it.....!
Is there a toiletry you can no longer buy and miss?
