The important thing is that the setup is there for a Robin who was living at home with folks and with another life.
The same can be said for Tim. He may as well have been an Orphan. He spent a good deal of time on his own or away from home at a boarding school.
There was little parental supervision that Tim was able to get away with spending much of his time at the cave training and was able to conduct his nighttime activities as Robin with out his folks ever noticing.
