I am upset that people 100 years from now will have no idea who I am? Was or thought? I will just a be badly decayed grave stone in 250 years. Does it upset me? No.

I lived in my time and they shall live in theirs.

But what is time? A great conspiracy I think. Time to grow old. Time to get married. Time to die. What else is left? I never wear a watch for exactly this reason....
Call me parnoid.
