We're all humans. We do things we don't mean too. We say things that have double meanings. We do things we don't know the outcome for. And we live everyday by day.
We love, we fight, we cry. We shout, we whisper, we communicate.
But not everything stays the same. The grandmother who took care of you and treated you as her son is now in the hospital. The mother that would get mad at you and would make you sleep early and wouldn't let you do whatever you wanted; she got in a car accident while going to work so she can support you and pay for everything you wish for and need. Your sister, she left she is starting a new life and moved in with her new husband.
People who love you tend to make you the most angry. The people who you love will make you love and miss them when they're not home.
Stop being a spoiled brat. Cherish what you have, the things that CANNOT be replaced. This doesn't mean you have to love everything and go to church every Sunday. It means to love what is given to you.
