Last Friday as Little O jumped out of the car and started to run to the door he looked and saw two girls being walked to school by someone's dad. He waved to me and then ran to the door. He then held it open and waited for probably a full minute until those two girls had gotten inside. He gave me my wave and started to go inside when he noticed another girl coming so he opened the door and held it again and waited until she was in the classroom before he followed behind. Neither Allen or I remember teaching him this.
What a proper little gentleman.
