Oh, I'm working on forgiveness -- defined as "giving up hope for a better past." The name change was basically a final eff-you to the old guy, with the added benefit of helping my wife feel more secure, by adopting her maiden name as my middle name. We had a few bumps in the road over the past 2-3 years, and I think this helps her put them in the rear-view mirror.
As for my Dad being sick, well, he would certainly have a few choice words about that... but in any case, that's where the "giving up hope for a better past" comes in.
