There are more reasons to Smile...than to not.....
If everyone could remember that there being mad or sad never makes the situation better....But smiling and keeping a positive outlook on life....The world really could be a better place.

So instead of looking at it as not smiling because you are sad...or that you don't want to let someone down....Why not look at it as...I'm going to walk around and smile...because you know that by you doing that...It will make other people smile....

(When you smile it makes me smile)
