How to respond to a gift of charity?
My wife and I recently closed a business. An acquaintance, the parents of our daughter's friend, were very sad to see our store closed and gave us $300 in cash. We've seen them at various school events over the years and they've been occasional customers of ours, but we are not particularly close.
What should we do? We feel kind of funny accepting such 'charity,' (we don't need the money), but we don't want to hurt their feelings either.
What's the etiquette on this?
Thanks.
