Short and Sweet

This week's poem comes from Marianne Moore (1887-1972), entitled "I may, I might, I must". I could not an official link to it anywhere, so here are the 4 powerful lines in their entirety:

If you will tell me why the fen
appears impassable, I then
will tell you why I think that I
can get across it if I try.

It may not seem like much, but for me this week, it will do nicely.
