Avoid both at all costs. 

In yourself and others.

Do not be insolent - impolite or lack respect for other people.

Do not be arrogant - excessively confident, inflating your own worth or importance.

You should always avoid insolence in others and arrogance in yourself.

May you always be humble and modest and be surrounded by courtesy, civility and politeness.

Wishes for a great day to all,

Each one a gift,

David/
