Some people say that you become what you are surrounded by. This is true. The more you hang out with someone the more you begin to act like that person. The same is true with your home life. If you are surrounded by a big loving family, you'll learn the importance of love in your life and you will be more loving toward your friends. Some people prove this to be right. I am an example. I am just like every other person in my family, not because of my genes but in how I treat people in my daily life. My family isn't exactly "lovey-dovey" but we tell each other that we care and we always have to celebrate birthdays and holidays and any other minor occasion doesn't go unnoticed.
If your friends always hang out, sometimes you develop a "dependency" on having that time with your friends. I speak from experience. This summer I didn't go more than a week without hanging out with my friends. But the same is true when you don't hang out with people. You start to enjoy being alone, and for some us that creates a problem when you have to go back to school...Everything around you is what makes you who you are. It's the reason why we have these things around us- for us to become who we are meant to be.
