I am heartless--if I don't like it, out it goes--straight to the charity shop! I do get pangs of feeling badly about it, but I am a big beleiver in feng shui, and it's really, really bad feng shui to keep unwanted gifts in your home--even tucked away in a box somewhere.
I am usually like this. I think that it is a lot easier with my family because they are used to my tastes more, and they truly are giving a gift to make me feel happy (and vice versa). My family might be lacking in a lot of areas, but generally speaking, in gift giving we are not. I am so glad that we were taught these skills, because I know hard it can be sometimes to figure out gifts that are thoughtful and useful for some people. I am not saying I always get it right because I don't. But I want gifts to be something that people at least like, if not love. It doesn't have to be extravagant at all, and my gifts rarely are.
I think my MIL thinks that every material thing given should be appreciated and kept forever. She can rattle off what she gave to my sister in law when she moved out of the family home 25 years ago. She has tea towels a former employer gave her that are ratty and holey, but she says she won't get rid of them because they were a gift. She has this really strong belief that almost everything of hers is valuable and
worth a lot of money. She also saves total rubbish in case she needs it some day.
When I moved into a studio flat about 8 years ago, I had to learn to not be so attached to stuff. It came in handy a few years later when I moved here. I try to keep one or two things that people have given me that are useful or I love. I will keep more than that if it is really useful or really something perfect. I don't think that most people give gifts as a burden, but I often feel burdened by the sheer load of stuff that was dumped on me (and packed away until we moved). Now it is up to me to figure out what I am going to do with "my stuff". Some of it is still there, and I am not going to bother with it. When it's discovered (if it ever is), then I will deal with the fallout then.
I can find humour in it, but the accumulation of massive amounts of sheer crap by my inlaws (and what they expected me to take) was one of the reasons why I was so unhappy the past few years. And deep down I think that I want them to love me, but I am coming to terms with the fact I am going to have to settle with them putting up with me. Whether or not I graciously take their stuff and display it proudly in my home isn't going to change that. If she doesn't complain about my lack of appreciation of the 30 demitasse cups she gave me as part of my wedding gift, she will complain about something else.
