"The opposite of love isn't hate. It's fear. You can't hate something or someone you didn't once hold passion for, someone you didn't let into your heart." Courtesy of the assistant headmaster at my high school in my senior year, while teaching a course in classical literature. I believe this was specifically in regards to either Oedipus Rex or Antigone. This was what broke me out of a depressive spell and a significant period of self-doubt, and ended up with me leaving high school behind on good terms with just about everyone in my class.

Barring that? "I love you and I'm proud of you". My stepfather, at about 2 AM on the day after my 19th birthday. Two months prior we had discovered he had terminal cancer. I said "I love you too". The following day he had a stroke. He never regained consciousness and died three days later, in our living room, on a gurney. That brief exchange was the last conversation we had.

I, uh...I'm gonna go take a break from the computer for a bit. Don't neglect the chance to tell the people you hold dear that you care. Nothing is guaranteed. Not "18 months". Not tomorrow. Don't be afraid. Love each other.
