They sure love talking about themselves
Most people around me sure love talking about themselves during casual conversations as if their life story were so amazing. When I try to sneak in something about my life in the middle of their story which kinda similar to their stories, I can see the sudden obvious disinterest through their body languages. They will start looking at their watches, clock on the wall, smartphones or yawning.
It makes me wonder how people can be so self-absorbed and have no shame, thinking everything in their lives just revolve around them.
I always try to identify and judge what sort of people they're by how they talk during conversations and treat them which they prefer best so I keep asking questions about them until they run out of things to tell about their lives.
If you're this kind of person, please be humble and stop this behaviour.
