When you’re the parent of a teenager who is dropping your child off at a friend’s house, you wait until they are in the door.
This is what you do. You are a good parent.
The teenage boy is absolutely horrified by this, especially if the friend’s house belongs to a girl. This is when the child flails their arms wildly trying to get you to leave before the door opens.
We call this the “OMG Dad You’re Annoying” wave off.
Thank you Collin for recently refraining from such wave. You are growing up so fast.
