This past winter, a pair of neighbors dug me out of a snowstorm*. I was incredibly grateful, as it was very deep and it would have taken me days to do what they did together in about two hours.
I found out from another neighbor what their favorite restaurant was, and bought a giftcard that would more than amply cover a meal for two. Then I put the gift card and envelope (D'oh!) In a box of dark chocolate cocoa.
I presented them with a thank you card and a box of hot cocoa with a ribbon. I didn't say, "check inside". I wanted it to be a pleasant surprise.
Weeks went by and I didn't hear anything. I don't expect a thank you for a thank you, but I began to wonder, maybe they don't like hot chocolate, and that gift card is going to waste in a box? I asked the first neighbor if they had gone to the restaurant, to which she replied, not that she knew of. I didn't want to tell the neighbor I had asked because it would, to me, have appeared that I was trying to make myself look generous.
If you have surreptitiously given something of value to someone and have received no acknowledgement of it's receipt, is there a way to inquire about it without appearing to want gratitude or recognition?
This would cover gifts sent by mail, a surprise gift sent through Amazon, etc.
*(There is some good to living here! This is but one example.)
