We as human beings sometimes forget that kindness is a good thing. If someone helps you with something, don't forget to thank them. If someone is being nice to you for no reason, return the favor. If someone makes you mad or upset, do not just stop talking to them, tell them why and what they have done to upset you.
I am guilty of these things because I am human. But, I can strive to be a better human than I am now by showing random acts of kindness.
As always, may the Force be with you all.
