Not all the time we're kind. Kindness has a limit too, because they will take you easily and take advantage of your kindness. Never trust anyone easily.
 If you can't stop being kind to others even if they treat you trash already. YOU MUST THINK ALREADY! CHANGE NEVER COMES TO THOSE WHO ONLY CARE FOR THEMSELVES. SELFISH. STINKY. 
  I'm sensitive sorry. Hehe

Just remind yourself
*BE KIND*
