Monday was the day of appreciating David Bowie on my Facebook feed. That’s the way it is when people die; until that moment, you can, if you’re inclined to, say their best work is behind them, they were never that great anyway, etc etc. Afterwards, for a while at least, it’s pure appreciation, love, honor.
Why do we do it that way? It seems totally backwards. For my own part, I want everyone to appreciate me and tell me I’m great right now, while I can enjoy it. And if you think my work is overrated and anyway I’m kind of a jerk? After I’m dead would be an awesome time to bring that up. You have my permission, go for it.
