Dreams or Not at Night

As if 

Until

I'd had one

I wouldn't really

Be human,

And until I hadn't had one at some point,

I wouldn't remain.

I didn't have one last night.

Now I guess I'm covered.

Non-Euclidean Geometry

I love this shirt,
its grid lines in shades of white and light blue
spreading over a dark blue field.

Short sleeves don't usually suit me,
but I'll wear it for this:

It makes me feel like a math teacher,
forever quietly trying to help people understand
non-Euclidean geometry.
