Funny thing about heritage.
A person is free to be ignorant of it, or just ignore it, and any ties to the deeds of their ancestors.
That might come in handy if your grandpa was a notorious murderer and horse thief, but sadly, it also works where people don't conceive of meeting with those who went before them some day and answering as to why they did nothing while the accomplishments their ancestors made were ignored or destroyed.
All you need to do is imagine meeting them one day.
