Etto

We go to the library often. Today we went for Mother Goose, a half hour with songs, a story from a book, and a puppet show. We park in the underground lot which echoes very well. Joseph loves to yell to hear himself. Samuel usually makes a noise but it is not typically loud enough to hear the echo. Today he said loudly, "etto." Immediately after hearing his "etto" he put his pointer finger to his mouth and started to say "shhhhh."
