Life's Questions Part 2

Ok, here is the second set of some life questions I have pondered...

Does it matter if you roll your chapstick down or leave it up? I'm an upper, Erk is a downer.

Is it necessary to wash your hands after going to the bathroom IF you are getting in the shower directly from the toilet?

How long do you wait behind someone at a green light before you honk at them to move it?

Can you ever get rid of a bar of soap completely? Really think about this one, can you? The little shreds that are leftover and get caught in the drain...

Does turning the water pressure up on the faucet really get the water hotter faster?
