The comfort I have now is that I DID tell you how much you meant to me, before it became an “I wish I'd let him know...”
In no uncertain terms... you are one of the two or three most important friends I have, you mean the world to me, I trust you implicitly, you are one of the coolest people I know, you look great, what you're doing is amazing, I really appreciate all the things you do for me and the times we have, I would follow you anywhere...
Maybe it seemed over the top at those times, but it was all heartfelt, and now I'm glad I made it known. Maybe while you sleep you can think of these things. Maybe when you wake up you can look forward to those times again. I am clinging desperately to those tomorrows in the meantime. And I'm keeping the “that's probably one of the best compliments I could get” close to my heart too.
And everyone else, take the time to tell the important people in your life, what they mean to you and how tall they appear in your eyes, how you couldn't do it without them, how you are a better person for knowing them. So the tough times aren't filled with “I wish I'd let him know...”
These days don't seem so grey, knowing I made myself known.
