What I will tell you, son of sons, is this: shortly, if not already, you will begin noticing the blackness inside us all. You will develop black secrets and commit black actions. You will be shocked at the insensitivities and transgressions you are capable of, yet you will be unable to stop them. And by the time you are thirty, your friends will all have black secrets, too, but it will be years before you learn exactly *what* their black secrets are. Life at that point will become like throwing a Frisbee in a graveyard; much of the pleasure of your dealings with your friends will stem from the contrast between your sparkling youth and the ink you now know lies at your feet.
Later, as you get to be my age, you will see your friends begin to die, to lose their memories, to see their skins turn wrinkled and sick. You will see the effects of dark secrets making themslves know - via their minds and bodies and via the stories your friends - yes, Harmony, Gaia, Mei-lin, Davidson, and the rest - will begin telling you at three-thirty in the morning as you put iodine on their bruises, arrange for tetanus shots, dial 911, and listen to them cry. The only payback for all of this - for the conversion of their once-young hearts into tar - will be that you will love your friends more, even though they have made you see the universe as an emptier and scarier place - and they will love you more, too.
