My kids are both older teenagers but still live at home. For the last few weeks, they've stopped saying goodbye to me when they leave the house, even when I'm sitting within 10 feet of the front door. They just leave. Yesterday, they said goodbye to a friend (right in front of me) who was staying over, but still left without a word to me. I take that back - they did say something to me, my son popped back in to ask me for a new chair! I told him that it greatly offended me that they would ask me to buy something but not bother to show the common courtesy of a goodbye, but today - not a word again and I was sitting right there.

Do I tell them it makes me sad? That I feel like they think I'm not important enough to bother with? When I think about it objectively, I realize it shouldn't make me feel so bad, but it really does. What should I do?
