My DD got a lovely boxed activity set for Christmas - but she already had the same thing for her birthday last year. The same company makes a range of different activity sets.
I have no idea where it was bought from, and don't want to tell the original giver that she doesn't want it, so I went into a local shop and asked if they would exchange it for one of the other sets.
They said yes, not a problem, and followed with "... it was bought here, wasn't it?"
Well of course i said yes, though I went a bit red! And now I'm going to take it back but I feel a bit horrible about it, like I'm being fraudulent (which I suppose I am). But really, it's an exchange and the shop can still sell 'my' item for the same price.
So why do I feel so guilty!
