The thing that recently really made me happy was one act of kindness. Last week I was walking down the street, and I found a homeless family, it looked like they didn't have food in a while, so I decided to go to the convenience store to get them something to eat. When I came back, I saw that one of their kids had fainted, so I rushed to them and gave them a bottle of water and the food that i bought them, thankfully the kid woke up, and the family thanked me for this, they said that the child didn't eat for two days and was about to die from starvation. I had no idea how such a small act of kindness could save a person, but it really made me happy, how I got a chance to experience this and realise the importance of kindness.
