Kindness

Surprise the people around you by doing something that they'll appreciate. For example, for your parents, do all of their yard work over an extended period of time when they're not home. Don't mention it to them unless they ask you if you did it. 

Or to your married friends with kids, plan to show up and babysit for them while they get a little date away. Or for your sister or brother that is going through a hard time, give them or help them with something you know will help remove some of the pain or stress. 

These acts of kindness will show them that you deeply appreciate them.
