At the memorial service for my dad, we piled all of the kids in the back of his vintage mint-green Ford pick up. There were a ton- he had two bio kids, one adopted (me), and five step-kids, most of whom have kids of their own. He also had four sisters, so lots of nieces and nephews and grands, plus friends with grandkids. I think of that beautiful sunny day and the back of that truck packed with happy, loving, laughing kids and think that is a great way to be remembered.
For a less abstract answer, I would like to be remembered as someone who tried to make things better.
