I really the mission of this organization. Remember that no kindness is ever wasted. We should be kind even if others are not. Kills each other with kindness. There are lots of inspiration quotes. Do not just read them. Do it. Be kind to others for it might be the only saving grace they needed. Don't be too quick to judge until you know what is the reason behind someone's attitude towards you. Don't be too hasty to reciprocate to what they show you.
There are those who suffer and in grief and pain but they hide that through smile or express that in harsh words and bad attitude. Pray for more understanding. If there is nothing good that you can say or do, then pray for them. There is always something that we can do and kindness is one of them.
Jesus came to this earth to show us an example. No matter what pain, humiliation, suffering and death that he experienced, still you can see how he treated every person with kindness.
A simple act of kindness is what this world needs.
