Smile though your heart is aching

You might recognize the title of today's post as the line of a song. There are so many songs about smiling, being happy. Out on a happy face, smiley happy people having n, and the one above, smile, though your heart is aching.
Smile at  yourself in the mirror when you wake up, it's the quickest facelift ever.
Smile at your friends and family. Smile when you go on Zoom, or whatever you are using.

Here is a quote by Mother Teresa of Calcutta about smiling

Smile at each other, amile at your wife, smile at your husband, smile at your children, smile at each other - and that will help you to grow up in greater love for each other.
