It's up to fate

fate  

/fāt/

Noun The development of events outside a person's control, regarded as determined by a supernatural power.

Personally, I believe fate is the reason why we meet who we meet, we do what life shoots at us and why we get involved in the things that we get involved with.

Fate is like death. One day we will all die. But we were put on this planet for a reason, and every single individual has a fate about what they do and who they meet. It's like for example only seeing someone once and there is no way that you could ever see them again, but you do. That is fate. These two people were meant to be in each others life's. Or you make a sudden decision to go somewhere or to do something and something happens that complexly turns your world upside down. That is fate.
Fate can not be changed no matter how hard we try to rebel against it, we will always loose. We were meant to do or meet a certain somebody and we will. fate has already mapped out our futures, it's down to us to live it.
