What do you mean I won't see you again

I had to say goodbye to all of my friends today, since I seem to only befriend people older than me...
It was rather heartbreaking, since one of my best friends lives with her grandparents, doesn't have a working cell phone, and doesn't have internet; it all worked out, I have a new Penpal from across town! I sure am going to miss everyone though, our days of highschool together have been lovely, and I'm scared of what'll happen next year, since my derp is off to the army. I won't have my lovely every day
