I can't even imagine how this must be for you. All I've got here is, friends who are old men and a grown son and - it's fine. I'm sure it's a lot. It is a lot. I didn't think that's what I'd learn when Remus and Sirius cornered me and told me everything.
It is my fault. Lily and me, we had one job, that was to protect you. And I get that we did, we kept you alive, but you were 18 months old. We should have been able to protect you for much longer than that.
