Kindness means to me treating others how you would want to be treated. It means going out of your way to help others when you don’t have to. I think kindness is being there for someone when they need you. There is a quote I love and I try to remember everyday so that I can maybe make a difference in someone’s day. “Be kinder than necessary, for everyone you meet is fighting some kind of battle“
If we could remember that, the word might be a nicer place. We are all humans, and also we have feelings.
Offering my seat up to an elderly person on a train or bus are some examples of what I do always. Letting someone in a queue go in front of me if they only have a few items is another example. There are so many ways you can help people. It should come naturally to you if you have been brought up correctly with manners.
