#2: Alternate between giving way and holding your own on the sidewalk. If you're that D-bag who always runs into people half your size just because you can, you might be surprised to be blind-sided by a 5ft girl some day...soon.
#3: Don't wear crocs. Or tall socks with small shoes.
#4: Don't walk slowly in Whole Foods. This actually isn't a pet peeve of mine--but M almost got his ass kicked.
#5: If you're an unnecessary asshole (see #4) AND you're wearing a suit, you are obviously going home to an empty, lonely apartment, and there is no hope for you. :(
