A Smile: Custom made, Free and will almost always be returned. The best currency in a simple non-verbal transaction.
Best Wishes: Wishing someone a great day, Happy Birthday or Congratulations never takes anything out of us. They only count if they are genuine.
Good News: Spreading good news is as simple as telling others you woke up this morning, you are healthy and intend to make it through your day with a positive attitude.
Greetings: It takes an extremely grumpy person to declare to themselves that they are out of Good Mornings and Good Nights to share with others and refuse to say it to those they meet. Greetings are common courtesy and like Best Wishes need to be said genuinely.
Love: This is not a romantic type of love, but the care and compassion you feel for those around you. It’s being interested in the things that make them happy and doing things to show them that they are important.
