Is it straightforward?
DS2 discovered pretty much from day 1 that he had nothing in common with his flatmates, & although disappointed has just kept himself to himself & was OK to go along like that for the rest of the year.
but apparently his failure to want to go out with them & get loudly drunk most nights is upsetting them
so they are now ganging up on him & he wants to get out.
Should he be able to get a room elsewhere easily?
