Well, we all know, that sometime one has to lose something in order to gain something bigger. We also know, there's no such thing as coincidence, that everything happens for a reason. Therefore, we can conclude that the reason why we lost something very dear to our hearts, is that there's a bigger plan for us that we can't fully understand yet. Sometimes, the only reason a person enters your life, is to make you see something you've been blind to almost your entire life. You should be thankful for having such a person in you journey,but also you should learn how to let go of them after they fulfill their role in you life.
