Glad you asked
People that smash glass bottles around camp fires,
People who leave camp fires burning,
People that leave disposable Nappies tucked/pushed under logs/rocks near Waterways,
People that flick their Butts out of car windows or anywhere else for that matter,
People who spit,
People who spit out their chewing gum,
People that grunt when asked a question,
People who scuff their feet when walking,
People who smack their lips when eating,
People who commit crimes against the young and elderly,
People who blame everybody else except themselves,
People who whine & moan about how bad their life is, but blame everybody else for their problems, but can't get off their lazy arse to do anything about,
People who talk loudly on mobile phones in public,
People who have no concept about personal hygiene when traveling on public transport,
Opening up a roadside toilet door only to find stuff spatted around the walls and over the taps,
Not much really.
