I finally talked to someone who had been involved in something major from like 2 years ago. Realized I had misconstrued some things, they realized their side had made some major assumptions they shouldn't have and that i had reasons to be upset in my own right. There were apologies, and I asked if they could pass along my apologies and explain on my behalf to the rest of them. Ended our talk on pretty good terms. I'm glad both that I finally got to say my bit and that I could realize and apologize for mistakes I made.
