Everyone needs time alone to reflect on the day they just observed. It puts a better understanding on why we do what we do. The saying to thing before you speak is very true because your words can reflect on you and those around you.
To be at peace with ourselves will give you a more joyful life and smiling definitely will make you live a longer life.
We all truly need each other to brighten each others lives. Its magical how things and make or break your day or someone else's.
Remember be kind keep your heart open it not only helps others by coming out bu/ you take alot in too..
