I don't so much avoid confrontation, but I do avoid people with whom confrontation is inevitable. For example, I have a brother with whom you can't talk to for five minutes before something outrageous comes out. I avoid him, and we never speak now. I don't have time for ignorance, or for people who are so self-involved they think they have all the answers, and everyone else who thinks differently is wrong.
Honestly, being the age we all are, but speaking for myself, I don't have time for anything other than enjoying what time I have left. I don't want conflict, I don't want arguments. I want to love other people, to care about other people. I don't want to spend whatever time I have left hating.
