I have people wanting to give me their used things. Some I take because I need it and I'm grateful but other things I don't like or need and I don't know how to deny things. So I take them and now I don't know what to do to them. How can I politely deny things without seeming stuck up or ungrateful. I have baby things sitting in my trunk and I don't know what to so with them because the people expect me to use it and see them regularly.
