It gets me down also NM. Sometimes we only see 'friends' a week before payday. They come round...drink our beer...smoke our fags and then scrounge the taxi fair home.
Oh...and then might as BF to borrow some money....rarara.
One pays back on the odd occasion....and I mean odd..! Other wise NO. Wouldn't even bring a beer round but they would then put on their facebook status that they'll be round ours for a party. A party we were not having and knowing she had no money as we'd already subbed her the night before.
