Dear Queenie,
My sister gave me a blouse for my birthday that was the wrong size. The receipt was in the package, so it can be exchanged without any problem.
Queenie, who should make the exchange, me or my sister?—Confused
Dear Confused,
You should. That way you can be sure to get the right size and the style and colour you would prefer.
You might also tell your sister – sweetly, please – about the exchange so she will recognise her gift when you wear it – and so she will know your correct size and preferences next time she shops for a gift of clothing for you.
