I'm a big Bob Newhart fan. I can't explain why exactly, but he is so deadpan, so even, he completely cracks me up. I was thrilled to discover he had a small role on Desperate Housewives!
Anyway, in some-or-other episode of one of his TV shows, he clarified that he doesn't stutter, he-he-he stammers. Having a friend with a son who stutters, I've learned a little about it, and stuttering is a complex neurological problem that's not well-understood and that varies greatly from child to child. Stammering, I think, is just repeating yourself a few times.
Katrina has developed a big case of the stammers in the past few days. She expresses herself clearly and has no trouble getting words out, but she repeats her first word numerous times: "I I I I I I I want to climb up on the chair!" It's like she doesn't want to lose the floor or something. As if we could ignore her! I don't think this is a problem. It just sounds sort of silly.
