First of all, I never knew that a 4 year old saying “first of all . . .” could feel like hearing fingernails on a chalkboard. Ricky has picked this up (cough *from Kevin* cough) and uses it when I tell him something he doesn’t agree with. It can be that it is time for bed or that he should not tackle Billy or that the dogs are not Pac-Man and he is not a ghost . . . if he doesn’t agree, he tries to debate his way out of it.
The only thing worse is when he then says, “second of all . . .”
