It's natural to want special people (like family) to share in our happiness. I think sometimes our regrets lead us to appreciate more what we have so I try not to think of it as a negative thing. Sounds as if you did right by your mother. What a honor to see you daughter graduate with a medical degree, congrats to her.

One thing I wish was that my father had lived to see America elect it's first African American president. But otoh, my children voted in that election and felt part of the process.
