Why does someone treat the new better than the old?

These days the longer you know someone the crappier they treat you. Just like clothes or any item, they rather treat the new like something special, interesting worth more their time than any before rather than the old that's been there for them longer and deserving of care for granted. Rather than fix it, we tend to say I'd rather replace. Am I just different, than everyone else but the eyes of God.Finding out someone's motives are not of your own, really hurts. Sometimes I feel like I was designed for a different world.
