A gift from my son

Thomas told me he would give me a surprise because of mother's day.He drew and cut a picture of a little boy with green shirt with buttons on it. He made it in the school. It's really cute, he told me it was a boy and would like me to have it, and he would make a girl picture for daddy on father's day. I don't know where that idea come from, but I guess he thinks daddy likes girls and mommy likes boys. This reminded me one time when he just turned to 4 years old, he asked me 'why daddy always like all girls ? I don't like girls ' because he has seen daddy greeting his teachers every time he picks him up. I told this to my friend and we laughed about it and she said you should tell him that you would love girls and couldn't get rid of them later on.
