It was DH's parents 50th wedding anniversary seven months ago, they had a party thing, to which my parents were invited and gave them a cheque for around £250 as a gift.
I just got a text off DH's mother saying that she went to cash said cheque today but as it had been so long since it had been given it had lapsed and the bank refused, she then asked me to ask my parents to write her another one.
I personally feel uncomfortable with this, as frankly my parents were incredibly generous with my PILs, I felt, and it is not their problem that MIL has took seven months to take the cheque to the bank.
AIBU to not ask them to rewrite the cheque
