Collateral

If you are a believer of fate and destiny, you would have consider that everything happens for a reason.
You being here is a collateral to others on this very planet. Everyone is bound for something and this might affect someone else.
You could  be standing at a bus stop doing nothing but looking at your watch, someone else could be looking at you and it could have reminded that very person that time is of the essence and he/she should hurry with what he/she is doing.
A singer/musician might be bound for something, but with his/her song and music, it could help you see something differently.
All this definitely have happen to everyone. We are a part of other people's life and some one else might be a part of our life even if we do or do not have interaction or connection with each other. We are here to provide/ assist/teach others something. We are never one and alone.
