I'll tell you the difference since you asked; If you wanted to eat a hamburger, and i handed it to you with my hand.. you would eat it...

I really hope i don't need to finish that thought for you.

I swear this is where the saying 'Don't know your arse from your elbow' comes from.

depends on which country this is and with which hand. the left hand, i would probably take offence, despite being left handed myself.

IIRC I read somewhere that in some places people use the right hand to wash their bums, open doors, shake hands, and other dirtier stuff. Left hand is used when needing tottouch food and other cleaner things.

The other way around :)

Oh dear..

So the left hand is for dirty work, and the right hand for clean?

But why do we shake hands with the right hand then? I guess there could be some "social respect" reason, but from a germs-and-stuff point of view it seems nonsensical?

The right hand is your weapon hand. So by offering it, you are stating that you do not intend to fight.

That makes no sense. Don’t you use your hands to scrub back there when you shower in the morning? If soap is good enough for that, why is it not enough for post toilet hand cleaning?

Edit; i just wanted to point out that i was answering the question whats the difference between your hand and your heiny not how to keep good hygiene for either. so with that in mind;

let me just, ahem, pass you a hamburger...

> Why is your ass different?

I don't go around touching people with it, or eating food; it's enclosed in fabric. That same fabric also makes it harder to fully air dry, which can be uncomfortable.

If I got shit on my hands I would do significantly more than spray it with a bidet.
