What has Hardened our hearts?

I write this note with deep thoughts
It came to my mind after i was in the clinic waiting to be attended my eyes met a beautiful little girl she kept staring into my eyes with her beautiful large brown eyes. she held a lolly pop : so i smiled at her and then she walked right towards me; used her teeth to break the candy into two and then gave me the half part of the candy i was amazed by her behavior. Then i asked her name then she smiled and ran back to the lady she was with!. I couldn't help but think what has hardened our hearts? why is there so much hatred ? why cant we be just like the little care free child who wouldn't mind sharing something as little as a candy? Yet the answers seemed so difficult!
Being an adult we think hiding the bruises we hold in our hearts is a remedy but that only makes it hard to see behind that mask and then we bear a burden of a secret stone.... but its not like that a child cries when sad and smiles when happy ..we don't have to prove were always happy. All i'm saying is sometimes under everyone's hard shell is someone who wants to be appreciated and loved. That when you plan to get even with someone, you are only letting that person continue to hurt you.That everyone you meet deserves to be greeted with a smile.
That one should keep his words both soft and tender, because tomorrow he may have to eat them.
That it's those small daily happenings that make life so spectacular. so cry if u have too but just know 1 thing i wont mind you crying on my shoulder .
