Friend came and visited yesterday and brought my kids an advent calendar (chocolate one) and another Christmas chocolate.
She showed them it and my eldest (7) said "oooh we have one of those advents" she then said oh I'll take them back for my granddaughter! And did 
My kids are 4 and 7 and today have repeatedly asked (mainly the eldest) why she took them back.
I said it's because you said you already had one when you should of just said "thank you", eldest says "well I didn't want to lie, but still wanted it mummy" 
AIBU to think taking it back was a bit mean?
