Kindness is never rated when you are doing well. Kindness matters when the chips are down and times are hard. In the end when kindness is expressed, it will leave the person receiving it with one of two states: thankful or resentful.
So, it matters little what the reaction is to kindness. Always do the kind and right thing and allow the rest to float in space and time. It is hardship to lay your head down knowing you have insulted or taken advantage of another. In the end, it comes back to you, in blessings or in the same way you have treated another.
Response to mercy and kindness should never be the factor for the act. You never know how a person will respond to you. They may be having a hard time, or life is dealing them a blow, or they are not good receivers. On the whole, it is better to be merciful than vindictive.
If ever you believe you are being wronged, offer an explanation but step back and away when it is not accepted. If you are shunned and ignored, they were never meant to be in your life for long. Never try to be right. It does not matter in the long run even if you are. As long as you have done what is right, sleep and rest in the knowledge and comfort of a clear conscience.
My prayer for you is this:
May you live many days to offer caring
May you rise every morning to give a blessing
May you fill your heart with mercy
May you use your wit for kindness
May your thoughts be filled with peace
May your mind remain at rest
May you lay your head at night in the comfort of a clear conscience.
