Some times, suddenly, you realise that you can't fight anymore. You just have to forget about the past, enjoy the present and dream about the futur. You can't live crying about how things change. You like how things were, and you don't want to admet how things are now. You don't want to see it. But it's time to realistic, live it's what it is, you can't choose, so live every moment the best you can.
You have to keep walkin, don't look back and don't ever give up. Take care of who you love, keep them close to you. And please don't cry. If they don't bother you're not gonna waist your time. So be happy, and love your friends as you do.
