Echos

Emma and I were outside today when she discovered that if her voice was loud enough, it would echo. This is how it went:

Emma "HELLO, AHHH, AHHH" very loudly.

Me: Emma, keep your voice down, Sam is asleep.

Emma: "I am yelling because there is a girl answering me in a strange voice, saying what I am saying. She is making me very nervous."
