Safe as Houses

Next year, I will be shunted from cosy university accomodation into a shared house, which is going to be a lot of hassle.

My problem is as follows: There is a person on my floor whom nobody particularly likes (including me, although I do sometimes feel a bit sorry for him). He seems to think that I am his friend, although I have given him a decidedly lukewarm reception. What happens if everyone else tries to avoid living with him next year? They will, perhaps, make it clear that they dislike him. It is virtually impossible to refuse someone something like that without offending them. Am I going to be stuck with someone I dislike for another year, simply due to politeness?

Social Etiquette, thou art a cruel mistress.
