There's a proverb that says--You may light another's candle at your own without loss. How true. When we share joy and happiness with others we don't loose anything. In fact, we gain much more in return.
If you light someones candle
Your flame can't grow dimmer.
Your candle will keep glowing
And retain its light and shimmer.
It's the same with happiness.
And if you smile to those around
Your happiness keeps growing
And new friends will be found.
