This has been in my head from pre covid when I was using spare room.co.uk and had gotten added to the digs list for our towns theatre; to try to rent out spare room.
Bf (10 years older, I'm mid 30s) said that above when I told him a female enquirer turned out to be wanting to book the room.for a week for her bf, (who was performing in a show in theatre).
We don't live together, I'm on a relatively low salary and was trying to supplement it.
(Incidentally he got the £x wrong because ot was a different rate for a week than as an ongoing lodger, but that's by the by).
Hes a reliable, committed, in some ways kind partner, but this is not the first time he's said something I'd consider tactless and Imo narrow minded.
