Okay kiddo, a poor person is someone who does not have enough money to buy things they need or want. Imagine you have some money in your piggy bank that you can use to buy candy or toys. Now, imagine if you didn't have enough money to buy any candy or toys. That's what it means to be poor.
Being poor means that sometimes you can't afford things like food, a nice house to live in, or clothes to wear. This can make life harder and less comfortable for people who are poor. They may have to go without things that other people take for granted, like going on vacation or having a lot of toys or clothes.
It's important to be kind to people who are poor and to try to help them if we can. Maybe we can share our candy or toys with them, or give them a little bit of our allowance to help them out. We should always remember that everyone deserves to have the things they need to live a happy and healthy life.
