What really grinds your gears?

Sometimes, the funny little things in life can just p**s you off. If you've ever seen Peter Griffin on Family Guy, he wasn't very impressed and even got on the news to moan.

Here is a list of silly things "that grind my gears" (in no particular order) and some more feedback from Peter:

toothpaste tube squeezed in the middle
people sharing "everything" on facebook
toilet seat up

packaging that is supposed to be easy open but it's a pain
reddit web page layout and design
dog poop on the pavement

people invading my private space
forgetting to send an email attachment
cling film

Why don't you let off some steem below and say "what really grinds your gears?"
