I'm new here. Why can't I do anything well? No matter what I say or do, everyone laughs at me.

This shows that you are far away from this society and probably just graduated. Freshmen who have just graduated have been living in a pure campus with simple social relations and little social experience. It is natural to join a group suddenly. They will often do inappropriate things and say inappropriate things and become a laughing stock. When you hang around for a long time and get familiar with all kinds of ways of the world, people will naturally stop laughing at you. Of course, don't mind this situation too much, which fully shows that you are still pure and have a heart that is not polluted by society. Of course, people have to grow up and mature after all. It's not a big problem for this to happen for a short time, but it's a bit dangerous for a long time. With more experience, things will naturally mature. That's how they got here.
