It doesn't hurt me feelings at all. If they are using it, that is great. If not, well, it was a gift and we all know we've been given gifts that you just don't care to use. I've been guilty of it too.
I know the quilts I have made for my grandmother, they are hanging up on a quilt rack(right next to my mom's...lol) and they don't get used often. I am glad she likes them and that she proudly displays them.
Here in my house...quilts get used. All of them, but the few I have tucked away that are getting really old and showing wear. My kids drag them with for car rides, sleep with them, use them to drag each other around, they are tents, ect.....they do get used. Everyone uses their quilts differently and different appreciation for them. Some are heirlooms and some don't think that way. I wouldn't let it bother you.
