Why am I outgoing and humorous when chatting with people online? Actually, I'm not very good at talking to people. I'm always dull and my mind is blank?

Because you are not confident in front of people, you are too nervous to correctly explain what you want to express ... Only in the online world, others can't see themselves, have no worries, won't be nervous, and naturally present a perfect state. ......

Regardless of the network and reality, you should have confidence in yourself, say whatever you want, there is no need to care and be afraid, no one will laugh at you ... be yourself, say whatever you want, don't say whatever you don't want, even if you are out of place, you don't need to cater to others!
