I feel like we're dealing with a bit of a generation gap here. Mark, I expect, was brought up with the idea: "If you hurt someone, you go to them and tell them you're sorry." The zeitgeist since then has shifted to the place where, if you hurt someone, you don't burden them with having to face you; you can make a public apology and they can respond to you if they choose.
I'm not saying that's a bad shift at all; for instance, a lot of churches have had the bright idea that they should bring together abusers and victims to talk things out, which is about 47 million different kinds of wrong.
But if Mark isn't really aware of that cultural shift and isn't used to it, that could explain what we're hearing here.
