It's funny, although I'm not in AA, and have only quickly read the Big Book, I find myself somehow doing amends, and contacting people again I should have contacted long ago.
You know how families can be complicated. Well, I haven't spoken to my brother for at least 20 years, but he has a daughter who's mum - my brother's first wife - passed away earlier this year. So I contacted my niece with my condolences, we talked a little more, and will see each other somewhere in the new year to have a good long talk. I have only ever seen her as a 6 month old baby, she now is a mom herself, so that's also a bit of a shock about time flying and all that.
Anyway, I think there is value in trying to correct some wrongs from the past, even if they are not directly related to your addiction.
