I'm trying to think of an anology here, but struggling....
I can understand what you mean joko, you have to pay rent to someone, and in this case the someone is your dad. No one has a problem with that at all. I don't think anyone would have a problem if you claimed housing benefit either. The "unfairness" to some of us comes about that at some point, your dad still gets his rent when your between jobs, paid for by taxes (ie, everyone else), your situation doesn't alter- and it becomes REALLY unfair when eventually that house becomes yours after we've helped pay towards it.. The timeframe of when you'll get it is irrelevant to be honest, you will at some point, that's a given. Would it be ok if the rest of us came and stayed rent free for a bit? Afterall, we've help pay towards it ;-)
