Two quick things to make the world a better place.

1) Elevators shall be LIFO. Last In, First Out. Women and children be damned. It's really annoying to watch people shuffle around to make sure the ladies get out first.
2) Do NOT drive on the freeway with your blinker on unless you are actually using it. It's not that hard, people. I know you're old, and it's harder to hear and see things, but if you can't SEE the FLASHING LIGHT, or HEAR the TICKING SOUND, you might not be road-worthy.

That is all.
