Sadness, much like getting hit by a bus, is funnier the farther you are from it. That means:
Life = bus
You (recent past) = person hit by bus (in pain)
You (present) = bystander in the fray (not amused)
You (future) = bystander watching from 10,000 feet away (laughing ass off)
It is small consolation to know that today's grieving will, with time, become tomorrow's charming anecdotes at some friend's dinner party.
