This year I gave my sister a £50 gift voucher for her birthday (electronic kind where they email you a code to type into the website).
She rarely gets me christmas/birthday presents and I could tell she felt a bit guilty about not having got anything for me for my birthday. However, what I've found quite upsetting is that she hasn't spent the voucher (been over 6 months). I've tested it on the website and it still works. I hate to see it just go to waste. Would I be unreasonable to spend it?
