Suggestions needed for odd question
Hope it's o.k. to post this strange question in this forum.
I am a widow (6 years) in my late 70's. Recently a couple from my church invited me to have Sunday brunch with them at a local country club. It was very elegant, and I assume, expensive. She made it clear it was their "treat".
To thank them (in addition to a note), I gave them a pound cake from a bakery specializing in such items. Now they have invited me again - I want to thank them, of course. I don't cook a lot now ( and I was never a good cook!), so I need to get them something.
I thought of flowers, but she has certain allergies. I could take them to lunch at a nice place - I am on a limited income, so I can't do that too often. I know they go to expensive places that I can't afford!
Should I refuse any future invitations? I did that once, as I did have other plans. I don't want to offend them, so I would appreciate suggestions.
P.S. They seem to have "adopted" me this year! Calls, cards, etc. He is a bit older than me, she is several years younger.
