You really do a great job of capturing the mind of these children at different ages. Bron's logic is perfect, and reminds me of a conversation I had with my three-and-a-half year old niece when I visited her family in Uppsala (Sweden) at the end of April: She stated that I speak English, which she knew because she had visited me here in London last summer, and I agreed that I did. Then she followed it up by saying "You do speak some Swedish as well, don't you?", perfectly seriously -- and all in Swedish. *grin*
