There are many examples of doing something nice for someone. Even though we dont need a week, its still a nice reminder!

Here is a good example:

The second Kindness Challenge of RAK Week: Smile at 10 strangers today! A sincere smile can really make a positive difference in someone’s day.  Without saying a word you are letting that person know that you see them and that they matter. People appreciate being noticed and acknowledged!  As Plato once said, “Be kind, for everyone you meet is fighting a hard battle.” Encourage ten strangers today by giving them each a smile!
