No TV, radio or video games during mourning?

When I was younger, I would dread there being a death in my dad’s rural Mexican village, they were super strict about the mourning process.

Tv, radio (pre 2000) and video games were not allowed for a few days until after the burial. We also had to cover all the mirrors in the house. The wake was at the deceased persons house and they also put some white powder in the form of a cross.

Is this just my dad’s village thing? A Mexican thing? Or what.
