Dear Leo,
As you grow and are challenged by life, you will gradually begin to notice that adult humans have collectively decided what is deemed appropriate sociable behaviour.
People (and this includes Mommy and Daddy) will tell you to say "please" and "thank you" and "excuse me".
Mommy has been watching you over the past couple of months, and has decided that this human etiquette stuff is actually a load of trumped up hogwash.
She is deeply envious and hugely admiring of your various activities.
