It was DS1's birthday last month. He received a card and some money from his grandparents (my dad and stepmum, who are in their 80s). However today another card for him arrived. Stepmum has been investigated for memory issues and been diagnosed with mild cognitive decline but to be honest my dad is not much better and very forgetful.
So, what do I do? Do I tell them they've already sent a card or should I just thank them and shut up about last month's card. This has really upset me for some reason and I'm so torn. Letting DS have the money feels like taking advantage, but I'm worried it will upset them if I draw attention to their memory problems.
