I like to give gifts to others as a way of showing love, so I really like the Christmas season and birthdays. I work hard to give gifts I think the adults in my life will like.
But one of my sons got mad when I gave him physical gifts. I gave him a mug expressing how much I care for him as my adult child and so on. And I bought a series of books for my sister's birthday. When I told her, she responded, "Why did you do that?"
My son told me I spend too much money, and he didn't have room in his condo for some books I sent him. Granted, the condo is small, but.....A few books?

I gave both sons the mugs because my mother never did anything like that for me. My husband approved of them.....

I am feeling hurt. What can I do in the future? Just send money? I can do that for my one son. SIgh. Suggestions? I don't know what their "love languages" are.....
