Nobody owes you anything.

I saw a post mentioning how nobody owes you anything which included smiling at you, etc., and that they can do whatever they want that makes them feel happy... and then I thought, I wanna discuss this thought because I personally agree with the fact that nobody owes you anything, but to a certain extent; because I don’t believe that people should hurt other people even if that makes them feel better about themselves, or make others feel bad etc. for their own good feelings. Like I believe there should still be respect, but I agree that nobody owes you anything - like time or making the effort for you etc bc I think we should put ourselves first (to a certain extent). Sometimes people just don’t want to do something like conversing back because they have their own life and feelings too and they may not be in the mood to talk at all and just want to mind their own business and not interact. It’s conflicting but I can see two sides of this idea that people don’t owe you anything. What are your thoughts???
