I often get upset and down over things that will never affect me. Like seeing some kid in the street with beat up trainers.. I worry his parents arent that well off and he has a hard time growing up. Or seeing a daughter nervously shop with her mother... she looks uncomfortable.. like she doesnt wana be there.. but is she only there because she doesnt have much else in her life.. not many friends or things to keep herself occupied. Seeing people stuck in dead end jobs.. like at a checkout.. you can tell by there expression that they want more from life.. but cant get it.
Its easy to be profound about it all... to sit and consider other peoples circumstances.. to the point of considering interveing and calling a person for example, just to sample their life.
It sounds like your unhappy in your life right now.. and your looking to offer people to compare yourself to. You say those girls dont exist... do you mean they dont live? Perhaps you feel like life is passing you by right now.
