Act of kindness that does not cost

An act of kindness is to help people in need or maybe not even that to sum it up  a act of kindness is doing something for someone or something that is helpful.I think that a good way to show kindness that does not cost is to help people in need like someone hurt, you could like ring the ambulance for someone in need or it. Or you could help a old person do her shopping or things like that. You could look after you ness or sibling or someone  that is younger then you. Maybe you could bake some cookies for people at the retirement home I also think maybe just saying hello to someone that is feeling down or chatting with them.Just helping someone in need is mainly what you could do.Maybe letting people playing a sport game that you a playing.The one that I would do is helping someone being bullied and standing up for them because they cant do it themselves and also sticking with your friend  and not ditching them and also helping with someone who is stuck on a maths question or something like that.You could even just help someone that is having trouble with walking because they have a injury and you could help them.
