We swore it would never happen. We promised to keep in touch every day and see each other every chance we got and we'd never let our friendships fade away into sweet nothings.

But then we grew up.

We went to college, we got involved, we took hard classes that took up all of our time. We got jobs, part-time or full-time, we worked odd hours and had to come in early or stay late.

Messages are sent and often read, but not responded to, and if they are responded to, it's hours after they're sent.

At the end of the day when we finally get home, we're so tired that we don't even want to do anything. We just go home, eat and sleep. It's like an endless cycle.

Trying to make plans to hang out and see each other often fails because our schedules are opposite, we're crunching time for deadlines and we have other things going on.

What used to be back and forth banter for HOURS has turned into one or two-word text messages every few hours with the occasional "I miss you," or "We should hang out more."

Nothing hurts more than not being in the loop anymore about what's going on in your life. Often times, we find out about the most exciting things on Facebook or Instagram, and when we ask each other about it, we say "I was waiting to tell you in person!"

Sometimes, I feel like the worst person in the world for letting friendships fade away, but at the same time, I know that school has most of my attention right now and I don't have time for much else because I truly do need to pass my classes in order to graduate.

I'm sorry for letting our friendships unwind, break and become nonexistent. I'm sorry that our lives have become so separate that we have such opposite schedules and it's hard to keep up with each other.

Believe it or not, I didn't want our friendships to dwindle away and it seems like we barely know each other. I wanted our friendships to remain like they used to: strong, beautiful and so full of life.

As we've learned, life doesn't always go that way. We get pulled away from friends and thrown into school, work and any other things that keep us busy.

I'm glad to see that all of you are doing well. I truly do miss you. Maybe when things calm down and we aren't so busy, we can reunite again.
