A couple is about to move in together for the first time.
The couple go somewhere to furnish/buy things for their new apartment/house. Usually this is IKEA.
They fight about furniture. Or is it really
the furniture they're fighting over?
They break up.
I'm not entirely sure there are enough examples in media for this; all I can think of is an episode of 30 Rock
and part of one of Louis C.K.
's more recent standup routines. However (1) I know for a fact this actually
happens (it happened to not one but two
friends of mine), so it may have appeared elsewhere. We might expand it a bit to other places couples moving in together might go after they move in together, but I suspect this might not be tropeable for a little while yet.
