Goodness me, I am trying to shake off two 20 year olds already. How bad would it be if they all got sent home if they ran into financial difficulties? 25 is like a proper grown up for non-student types.
I'm not accusing students of immaturity btw, just saying that if you've been working for 7 or 8 years and lose your job, losing your housing as well would be doubly shite.
