We cannot predict things, some happens unexpectedly. And it is what's exciting about life, we don't know what will happen next. You may be sad today and feel extreme happiness tomorrow. Maybe today you're in love and the other day, you're not. Being in love is one of the happiest feeling that you can feel, but does love really requires sacrifices? What if it's not the perfect time for the both of you yet? Are you willing to wait?
