A man bumped into me on the street.
He looked an awful lot like myself.
He didn't bother to apologize,
Instead he went on to say:

"Those who are anxious for  the future are afraid to die. Then there are those who dwell on the past. These people are afraid to live. Nothing quite feels like the present, it's ashame too few experience it."

After that he disappeared into the crowd of people.

I wonder if my time machine has a return policy.
