I believe many people got into a situation where they were the only ones laughing in a large group. People usually start staring at the person, making the situation more awkward.
How to avoid interruption of conversation, lecture, or some other verbal communication in cases where my laughing looked awkward?
This usually happens when I am among my groupmates in university. The last time it happened others started laughing too, probably because of me. Then people pretended that nothing happened, though there was still a moment of awkwardness.
What concerns me is the fact that I interrupted the conversation. I don't mind being stared at.
