double "parking"

Today we spent the morning had the playground with some friends. While we were there, a little girl probably around 2 years old was leaving with her mom. As they were walking by us we overheard the mom tell the crying girl, "Don't be sad... wave bye-bye park. See you another day." The little girl starts frantically waving and saying "Bye bye park... Bye bye park. See you." Parker right away looks over at the sound of his name and goes, "Byeee wittle girl. Bye." Then he turns to me and goes, "Mom, I don't know her name but she's weally nice."
