I was away for 15 years and when I returned no one met me at the airport so now I'm angry.
Why would no one show up to greet you at the airport?
I'm not sure, but they didn't support me at all and I'm pretty mad.
It sounds to me like the people who failed to show up just aren't doing all that they can to be a good people. You should tell them how this has made you feel and hope that they learn their lesson about not meeting you when they were supposed to.
So you don't think I should make a big deal out of it?
I think you should have a good talk with them. They really hurt you when they didn't show up at the airport. Just make sure that you stay calm when you are telling them or it might turn into a fight and allow them to justify not showing up to greet you.
