I was reading a book of facial expresions to my 4y/o sister, you know like happy, sad, confused...and when it got to the page where the kid was making a surprised face she paused for a minute. I was like "what face is he making?" And she informed me that he wasnt surprised, he was Astonished! I was like wth, how many 4 y/o's use the word astonished lol...?
