what is the science behind ‘masks help stop you spreading germs , but don’t stop you catching them’

This is something I’ve heard a lot, and assuming it’s true, what’s the science behind it? Surely holes in masks are the same size no matter whether the germs are heading in or out, but I’m guessing it’s not about the holes and I’m missing something.

Obligatory disclaimer: I’m not an anti-masker, I’m still wearing it in shops for example. This is just me wanting to understand.

Thes best thing i saw was the Pee in pants example.

Someone was about to pee on themself….

If you are wearing paints, but they are not you have a high chance to be contacted with pee

If you arent wearing pants, but they are they will pee thier own pants. if you are close enough to them you could still get wet but its unlikely

If both you and they are wearing pants you have the best chance not to get wet
