My half-crazy, drug abusing sister and her junkie boyfriend have fetched up in my mother's house in ireland with all of their luggage about a week ago. Sister's normal evasions and dishonesty notwithstanding, I've gathered that he has left the UK to avoid a jail sentence - yes, on the run from the law... So my mum's objections to them staying with her have been ignored by both of them, they are extracting her pension from her as best they can, and now want to use her address for their benefits (I am not clear what benefits these might be). I am terrified of confrontation but don't think i can allow this situation to continue. Anybody got any suggestions?
