Has it ever occurred to you that brilliant people speak to all kinds of people with all kinds of ideas to increase their fund of knowledge?

You can entertain ideas without accepting them.

You make so much money that you cannot afford to be kind to two people who have sacrificed two years of their lives to simply make the world a better place?

Shame on you.

Invite them in. Offer them some water.

Be polite. Be kind. Their religion teaches service and sacrifice. Their systems are effective and efficient.

You may learn something.

Life is too short not to be kind.
