I hate goodbyes

Today is my last day at the company I've been with for 7 years. I can't help but be a little sad to leave since I really did have fun there at one time and have met some really incredible people. So I have to keep reminding myself that it's not the same place that it was when I started and will never be that place again. I think goodbyes suck because you either know that you're chances of seeing the person are slim to none. Or because your relationship will forever be changed because of some life-changing event like when your friend marries someone you can't stand, or has a kid, or has a sex change (not that that's ever happened to me, but I'd imagine it would be weird).
