what really grinds my gears most of all though is people who can't write a bloody word properly,
especially on the internet, honestly, when I sign up to a forum to get some help I make my posts as clear, concise, and readable as possible, I try to put as much information in as I can, (I have problem A I have tried X, y and Z etc)... it really grinds my gears when people leave half a message with no detail that looks like it was written on a cell phone. and expect you to help them...
