Distrust is when you don't believe or trust someone or something. It's kind of like when you have a toy that always breaks or a friend who sometimes lies to you. When that happens, you might start to think that the toy will always break or that your friend will always lie, even when they don't. You don't trust them.
Sometimes, people feel distrust because they have been hurt in the past, and they don't want to be hurt again. For example, if you shared a secret with a friend, and they told everyone, you might not trust that friend with your secrets again.
Distrust doesn't always have to be about people, though. Sometimes, you might not trust something, like a new type of food that looks strange to you. You might think it will taste weird or not be good for you, so you don't want to try it.
In the end, distrust means that you have a hard time believing and trusting someone or something. But it's important to remember that sometimes, we can be wrong about our distrust. It's good to have caution, but it's also good to give people and things a chance.
