"Did you not keep track of which box that went into?"
I thought we'd agreed to write the contents of each box on the side - can you not find it that way?
Over there, I think (waves vaguely in no particular direction)
Along with the gin/wine/whisky/beer, I think.
It's definitely in the house somewhere...
Can't that wait until we've unpacked everything?
Hmmm, can that wait a moment while we have a cuddle?
While you're finding it, can you also look out the {fish kettle, or anything else you've mislaid}
Tell you what, shall we just buy a new one. I always thought that was a bit old...
