I just got a collection agency notice from a parking ticket I got in 2006. Yes, that 2006. That was two cars and four moves ago, and yet they have somehow tracked me down.
I know this because today I deviated from my normal MO and actually opened each individual piece of mail and decided on what action it required from me, then did that before moving on with my life.
This makes me feel way, way prouder than it should, but bracing oneself for the mail can be a tall order. For a lot of us, the mailbox contains 17 annoying and/or scary things for every one awesome thing (oh, hello there, happy letter from Margaret!) But you can’t opt out of it and ignoring it is not the answer. Just open your fucking mail already.
