I'm talking about human leeches, the kind who want to come and stay in your house just to eat, sleep and use the toilet (I'm trying hard to use polite language), and want to contribute NOTHING. They expect everything to be handed to them, want to eat and stay for free, expect you to use all your hard-earned money on them, and they use none of theirs on you. They want to receive, receive, receive, and never ever give. It's sick, selfish and disgusting, and I'm sure no one would blame me if I'm not exactly polite to such people. Agreed?
