How to impress your crush without talking to him?

I reckon it's about the little things, mate. You don't need big words. Just catch his eye sometimes. Give a small, quick smile. Then look away. Be happy with your own friends. Laugh a lot. He will see you are fun. When you are happy, you look good. Also show you are kind to everyone. Not just him. People notice that stuff. It shows you are a good person inside. Wear clothes that make you feel great. When you feel good, you look confident. He will notice that for sure. It’s not about talking. It is about showing him who you are with your actions. Good luck
