I remember my nan saying not to wash my hair on a Sunday. The trouble was - as a teen, I competed nationally in swimming. She was horrified at me swimming on a Sunday because of hair washing, even more so if I was on my period. No nail cutting on Sundays either.
New year's day and after Sunday always wear something new and eat well. It's meaning was that you'd never be hungry and be fairly affluent throughout the year. Any chores done on new year's day you’d do everyday for the whole of the forthcoming year.
Again, if clothes were put on inside out you couldn't change them until midday it midnight.
Collar holding with ambulance sightings. Never swallow, hold your collar until you see a four-legged animal.
No new shoes on a table. Even boxed was a no.
Funny thing is- when I asked why about all if these I was just told ”because you shouldn't”. Well, that cleared thing up nicely. ??
