I have come to realize that the so called introverts are the most fun filled people to be with once you can get them to free up with you. People like these don’t talk o interact, they have a lot of ideas, jokes and they do observe a lot.
So once you are able to get them to talk and pore out their mind to you, you will never get bored.
This is why I would agree with you that lonely people are not always bored.
You're right. Introverts are the most fun to be with when comfortable and they give the best jokes.
