Yesterday I picked up my new glasses. They look different than my old ones -- these are brown plastic tortoiseshell, and the old ones were wire frames.
Sam, my 18-month-old son, said "new glasses!" He's still a bit hard to understand some times, but he talks a great deal these days, and even sings us songs.
Isaac, my 13-year-old son, said nothing. When asked he claimed that he noticed but just didn't bother to say anything.
Does that count as noticing?
