Yes, one for sorrow, two for joy…. re magpies. But they weren’t protected then so not a common sight - now they’re everywhere, around here, anyway.
I didn’t really grow up with superstitions, apart from not walking under a ladder - but when later living among Greek Cypriots in the Middle East when I had babies, I heard plenty - or rather they were old wives’ tales.
If taking a baby out after dark, you must cover its face with a blanket, to keep any evil eyes away.
If I swam when pregnant (I was often in the pool) my bones would open and I’d lose the baby. (!)
If I kept on carrying my nearly 3 year old when pregnant, my baby would be born with a broken arm. (! again)
But all these were decades ago now - I dare say things have changed.
Another was In Germany when I was on my exchange visit at 16 - the mother was insistent that you couldn’t have a bath or wash your hair when you had your period - one night there was a real tantrum from her younger daughter who was desperate to wash her hair.
