He may be CHILDISH, but that
doesn't mean he's a CHILD!
I mean, what child would: have a
full time job, be learning how to drive,
have a house, have credit cards (as seen
on the episode with: Gary's Ball), AND go to
the store for THEIR OWN NEEDS? I think you
should get my point.
See, there's no logic in SpongeBob being a
child and does all those things (although, there is
hardly ANY logic WHATSOEVER in SpongeBob...)!
But, I think your getting the "swing of things"!
K.S.L.L, my friends.
