I do not think a Seasoned Lisper thinks in terms of S-expression at all, counting brackets and doing other such shit. In his mind he sees only the 3D representation of pointer trees. S-expression is just a way to represent this tree in textual format.

I always imagine 3D Lisp-evironment, where you only handle those trees with magical hand gestures like Tom Cruise. But this dream always fails when you go further details, like symbols and numbers: Why would use this archaic system of letters at all? Atoms should be just shapes and sizes.
