Went to DB for weekend took duvets and pillows as requested.
Coming home one of their kids pillows must have got scooped up with ours by mistake.
SIL wants me to post it back.
My initial response is: that seems crazy, surely you have a spare, or can buy a new one and keep this as spare when you get it back when you see us next.
Don't want to start WW2 though. SIL and I have form.
Should I just send it or is this a crazy request and will cost loads??
Am I beiiiing unreasonable?
