My student's response to being a Choice Mom

Yesterday at school, my students were in the computer lab typing letters to their pen pals.  I was sitting amongst them doing some other work on one of the computers and helping them while making conversation with the group closest to me.  My students are 8 and 9 years old.

One of them asked me if I was married.  I replied with, "No, my family is a mommy and baby family."  I heard one student mutter under his breath "oh, so you don't need...." and then another one interrupted with, "Your house must be very peaceful."  I found that hilarious.  I wonder what goes on inside his house.
