Donatello- flying under Splinter's radar?

[Scandia]

It seems like Donatello's named is not mentioned by Splinter as much as the names of his three brothers. Donnie hardly ever gets into trouble- and if so, it seems to be an accidental consequence rather than truly being mischievous. And while Donnie is a good Turtle, and a good student, and a good son, he is not the golden apple of daddy's eye either.

While Splinter does not deliberate ignore Donatello, it seems like Donatello gets the least amount of Splinter's attention, whether good or bad. Sure sure, Donnie is very independent and self-reliant. But how long would it take Splinter to notice if Donatello ran away from home? Or even if Donatello left the lair because he wanted to go to an event or buy something- would Splinter even care because Donnie is not a troublemaker and is not likely to go out to right wrongs either but just for personal reasons?

Does Donnie prefer it this way? Or does he secretly want more of his sensei's attention but realizes it is better to fly under the radar?
