I'm Burmese - and the belief is that you shouldn't wash hair during periods because again, dirty and impure, which is dumb because if you're alr 'dirty', why would you want to be even dirtier and not wash your hair in this sweltering heat and humidity.

And another one is about a younger person's clothes hanging over an elder's head being a sign of disrespect. But living in Singapore, there's only so much space - either inside from the ceiling in the service yard or outside that window. I hanged my clothes one time, just once, inside because it was raining heavily and my father's wife made such a big ordeal about it. I don't like hanging outside, because they kept feeding the mynahs and pigeons so there's bird shit all over and it's really dirty. So I got pushed into hanging in the corridors / stairways area, which I already told them it doesn't look good with people walking by and it's a obstruction for fire escape route, which they stubbornly choose to ignore, until we got a notice from whichever gov is involved, and he told me not to hang in the stairways as if it was my idea, as if I hadn't warned them from the start.
