MIL has a birthday coming up and SIL is taking her for a weekend away in a European city. SIL has asked DH and I to contribute to the cost of their trip "instead of buying a present that she won't want".
DH has asked my opinion. The amount that SIL is asking for is quite a bit more than we would usually spend on birthday presents, but it wouldn't cause us any great financial hardship to do it. My initial reaction is that she is being a CF to ask us to pay for their holiday and that DH should buy what he likes for his mum, AIBU?
