When someone tells a joke, you smile, but others tell the same joke. Do you feel disrespectful to others if you don't laugh?

This is actually related to your personality. Maybe you haven't met the right person yet. In fact, I am also more introverted, and I may open my mouth when I meet someone who is more in line with my ideas and ideas. You can reflect on yourself first. Is there one or two people you can talk to, or can't you talk to everyone? If you can't tell everyone, it may be related to your own heart and personality.
