This. I mean, I could buy the idea that maybe Babs doesn't have that same deep-seeded need to create a family around herself or something, the way it could be argued that Bruce does.
But at the same time, I've often thought that the lack of female mentors and friends in Babs's life prior to becoming Oracle is largely what motivated her to seek out female agents for her own team, and why she does have a tendency to mother people a bit.
IIRC, you had a post a while back about Babs and Bruce, cave vs. nest, etc. Bottom line is that if Bruce is a patriarch of heroes in Gotham, Babs should be the matriarch, and have a similar legacy.
