People hearts are hard to predict. It is not because someone is hiding or avoiding getting exposed, it's because someone doesn't even realize what's deep in there!
Hearts keep changing and feelings keep coming then going. People hearts are like the day, they have morning, afternoon and night; they do love then they do hate, they are hot then cold, they are extremely warm and wide that they can hold the whole world into their arms then they turn into the cold ice that can't be lived close to.
To trust someone's heart is like gambling, there are no guarantees.
When you love someone, let a space for getting hurt. When you hate someone, let a place for a possible coming love.
When you cry because of someone, smile because the end shall not be written with tears only. However, when you have a happy moment, forget it all and live it till the end, enjoying happiness needs no calculators. Lovely stories continue when you believe that they can last forever.
Live, Love, Hate, Breath, Promise and Leave, but never be alone just because you've had enough of their fickleness. Try to understand and learn more about them, then you will gain much more than what you may lose. People are strange sometimes, yet don't forget that you are a person of people.
