Rule 11. Smile genuinely at people passing by. (SOMETIMES!)

11. Smile genuinely at people passing by.

The occasional, “How are you?” might even be in order. 

 
This is a BIG one. You could be making your first impression without even knowing it yet. 
*Kids, Dad here, This is your Mom’s Rule. It worked out well for us. BUT be careful, I don’t recommend this in the following areas:
-Scary Parts of the Inner City 
-Prison (better not be there, but hey nobody’s perfect)
-In a zoo, that is a sign of aggression and you will get your face eaten by a Chimp. No thanks.
– Scary Biker Bar
– Basically anywhere scary.
