Wonderful idea for a post Dan. Thank you would be a good one to teach - Ha! Tobie seems to understand "When" to say something more than "What" he is saying. He can be uncanny in his use of words or combination of words, or just not get it at all. He clumps his greetings and salutations and when I leave in the morning and say "Bye Bye" he sais "Hello". He is either trying to tell me something or thinks the words are interchangeable. We play a game called "what time is it" Tobie will ask the question or I will ask the question "what time is it" and the answer might be "bedtime", "suppertime", "dogfood time", "Morning time" etc. He has a new you tube video in which he nails this one. He isn't always right though.
