Or say things to hurt you?
I'm trying to think of something profound to say here. I've had all day and most of the night to think of the right words. The ones I know you've been waiting for. That magical combination that encompasses "I care about you, above all." "I'll miss you." and "You don't have to feel guilty. I'm okay with this."
English is a language of guilt, it's tailored through long years of hard usage and rough handling to convey the broadest ideas and dance over the nuances of meaning. To say "It's for the best" carries with it an unfeelingness. To say, "I'm glad we had this time together" is to convey an ending I don't feel. To say, "There's no one like you, it will never be same," is true, but bears a heavy burden beyond what it needs. Everyone is different. Nothing will be the same, but it will still be. And it will probably be excellent, given time, but to say that sounds like I'm cheapening your value, and now we have it.
So, in conclusion it seems fitting to hand off the responsiblity of profundity, as I find myself inadequate to the task.
Looking out into the pond,
No one leaves for good.
