The text of the postcard is

Dear Ellen,

I decided to rate, in order of size, the following words which convey size without specificity:

A few
A lot
Like, a gajliion
A ton
A *#&t ton
a gajillion (the word like, above, decreases that)

Rest easy world, things ought to make sense now!

Sincerely,

Why am I doing this?
