As you go away to college you will make new friends and hang out with different people. It may get harder to keep in touch with your friends back home, because you're busy and they're busy and sometimes your schedules just don't match up. But, they're your friend and they have been there with you for a decent part of your life, it wouldn't be right to just let your friendship fade because now things require a bit more effort. So, yes, feel free to make new friends. Heck, go and make a new best friend. But please don't forget about your old friends. And, after reading this title I'm sure some of you recognize it. It's actually part of a Girl Scout's song which reads:
"Make new friends,
but keep the old.
One is silver,
the other is gold.
A circle is round,
it has no end.
That's how long,
I will be your friend."
You're around new people in college, your horizons have broadened. You are bound to develop friendships and most of these friendships will in fact last a lifetime. Or as the song says, some of these friendships will last as long as a circle, because "A circle is round, it has no end."
No friendship or relationship will work without a little effort. It's a little give and a little take. Try and set up times that work for you and them, and keep trying. Keep trying until you've exhausted all possible resources to keeping in touch. It's not worth it to lose someone that once meant so much to you. Sure there will be people that you just don't keep in touch with anymore, and that may be because they were only your friend because you saw them at school everyday. But, the ones that really matter, those friends you truly cared about, push a little bit harder with them to keep the friendship going.
And if you get the chance, introduce your old best friend to your new best friend. They already have one thing in common, that's you. So don't give up quite yet. Make your new friends, but also keep your old friends.
