Cleavage

One of my students comes to school in her PE clothes and then afterward changes into her 'school clothes.' Today she ran to change and came busting into the classroom saying: "I found my cleavage!" I turned around and she was wearing a shirt that was lower cut. Needless to say, the shirt was adjusted. This is really funny because this student is socially on a 3 or 4 year old level and totally didn't get what the big deal was.
