A simple "Thank-you" for any gift is common curtosy. But after that, if the person doesn't like a gift I give them, I tend to see it as my own shortcoming, not theirs. I have always enjoyed gift-giving and gift prepairing. Weather it's homemade or store-bought, I have always enjoyed the whole process. Trying to figure out what the person needs or wants, buying or making it, wrapping and packaging it, and then finally getting the joy of giving it to them. If the gift doesn't "fit" them, I would be disappointed in myself that I missed the mark.
Having been married less than two years ago, I know what it's like receiving gifts that aren't me. I'm very thankful that anyone would think to give us something. But we definitely received a few gifts that left us scratching our heads. One was a Waterford Crystal cake stand. The kind you can flip over and it becomes a punch bowl. It was very beautiful and I'm sure very generous. But it completely doesn't fit my husband and me. We're both much more simple than that. I would feel very strange displaying our Entimans cakes and Chips Ahoy cookies on something like that.
Months later it was still in the box, and I felt like it was a waste for it to sit around not being used. I gave it to a friend who holds a silent auction for a local charity every year. I don't know if the gift-giver would approve of this, but giving something to charity is much more my style than keeping this fancy dish around the house. I'll echo what others have wrote in that once the gift is given, what is done with it is up to the receiver.
I'm sure we've all received gifts over the years that do not suit us. And I'm sure many of us have faced pressure to use or display those gifts I just try to remember that feeling when prepairing and giving gifts to others.
