- turn up to someone's house to pick them up and honk their horn instead of getting out of the car and knocking on the front door. horrendously RUDE and vulgar.

- dont turn lights out when leaving a room

- leave their rubbish bags outside their door for days rather than taking them out and putting straight in the bins

- dont make even the minimum effort to recycle properly

- leave their bogies to dry on the shower door *puke*

im sure there were a few others i had in mind...
