Yesterday, the tall person shared his ice cream with Barnaby and me. It was the first time that Barnaby had eaten ice cream.
I explained to him that we have rules concerning ice cream.
Rule 1: Wait patiently and do not panic. The tall person always shares but if you pester him there is always the possibility that he won’t.
Rule 2: Try not to watch the tall person eating his ice cream. It is best to look away or you will start drooling.
Here I am demonstrating the correct observance of Rules 1 and 2. Note that Barnaby is flouting Rule 2.

Rule 3: When the tall person indicates that it is time to share approach the ice cream carefully. Ice cream is notoriously slippery and can easily fall on the ground. A gritty ice cream is not much fun.
Rule 4: Do not rush. Savour the cool, creamy texture.

Rule 5: Try to avoid an ice-cream headache, also known as brain freeze, cold-stimulus headache, or its given scientific name sphenopalatine ganglioneuralgia (meaning “nerve pain of the sphenopalatine ganglion”). This is a form of brief cranial pain or headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream.
Unfortunately, as you can see from this picture I ignored my own advice and suffered sphenopalatine ganglioneuralgia. Ouch!

Rule 6: Ice cream can be very messy to eat. Always maintain your dignity and avoid looking silly.
Oops! Have I got ice cream on my nose?

From the look on his face I think Barnaby enjoyed his first ice cream.

Follow these simple rules and you too will maximise your ice cream eating experience.
