Well, for me, the first one that comes to mind is when I'm walking down a sidewalk and there's three people or more walking towards me and they don't have the normal common respect of making room for me to pass by. They'd rather ignor me and have me go around them and walk across the grass.
I don't think so .......... It's simply rude.
So, I just march on right through the middle of them. It usually wakes them up pretty fast! I'm a big guy.
Regarding socks ............. that's one of life's drags!
