Define "limits of infinity."

Dear digsalot,

I have found the "limits of infinity" ... today, when I was standing
in line in the post office with the entire town before me. I stood
there for a time span that seemed infinite to me - and yet I obviously
left the post office again (otherwise, I wouldn't sit here at my desk
and write this). I therefore believe that the limits of infinity are
defined through a complex mathematical formula that includes the
laziness of the post officials behind the counter, the endless stupid
questions and desires of the people standing before me, and the fact
that the person standing directly behind me has always eaten a pound
of garlic.

Oh, by the way - I had to pay $3.60 postage for the letter I sent. But
that's not important, I think.

Greetings,
Scriptor

We have slow postal lines here too, as well as garlic eaters.  Have a
great holiday.  Buy some snow. Perfect answer.

Cheers
