taking the longer route

From up I went down

Then I went back halfway

Walked a few steps diagonally up

Then got back

Just to walk a few steps diagonally down

I slept

From down I went up

Walked to the right

Went back

Walked down halfway

Walked to the right

Then back again

Went back where I started

And walked to the right

I slept

Once again I went up

Walked down diagonally

Then up again

I slept

Only on the fourth day

Did I realize

That  walking in a path

Of an inverted triangle

With a base of a Double arch

Would mean just the same
