Actual conversation today.
Me: We need to replace the roof and the pitch of the extension straddles the party wall. The concrete is loose and needs replacing. We're happy to pay for it if you agree to the works.
Them: I'll need to talk to the party wall surveyor about this and see if he thinks this should be formally agreed.
Me in my head: OF COURSE HE'S GONNA FUCKING THINK IT SHOULD, BECAUSE HE'LL GET PAID AGAIN. FUCK YOU AND YOUR FUCKING WALL.
