what difference does it make if you step on somebody's spit? poop i get. but spit?

HFCAMPO asks people to remove their backpacks before they can enter his home.

Taking off shoes in the house is also the norm in South Asia, the Middle East, at least some of Central Asia, North Africa, and in most of sub-Saharan Africa (I think). It obviously keeps the house cleaner. It's also practiced by many in China.

Spit can spread some diseases. Flu, Epstein Bar virus, viral meningitis, Cytomegalovirus (CMV), to name a few.

Do you really want to drag someone elses mucus into the house.

I dont know if I should love this guy or hate him - but he sure does make me laugh.

'Do you really want to drag someone elses mucus into the house.'

NFW (no f***ing way)! I have enough issues with my own mucus. In fact, my mucus has issues!

However, isn't just about every spot you step on outdoors potentially 'dirty'?

And the second part of my two-part question is: who in their right mind allows their lips to come into contact with the soles of their shoes ?

You walk it into the house. Other things touch the floor, including kids and their toys. The rest is done by hand to mouth.

some people act dumb, otherse just are

i guess you need to wash the floors regularly with kids around. and maybe adopt the local custom of no shoes in the house. but the fact is, the minute you step outside, the shoes are a potential threat, spit or no spit.

@Magnificok, come on man, please don't tell me that it's only today that you've become aware that people's spit can carry tons of germs, disease, bacteria...

Pee, poop, ptuh. I don't want other people's nasty in my home.

my point is the streets are filled with germs, aren't they? but yeah, if you step on shit or spit, you're practically begging for a disease.
