Bruce and Dick kinda just happen. A natural mix of two orphans who lost their parents to crime, crime fighters, mentor-apprentice, brotherhood, guardian-ward, maybe father-son but they never say it. Two people having fun and make the best of their situation.

Then before they realize it, Dick has already grown up and left the Manor. So Bruce also felt like it's not needed anymore or that it's too late.
Late, but still before Tim and Cass.
