Costive: (adj) Slow to speak or act, stingy, constipated

Maybe the reticence melts away:
When I sit here beneath the skylight
The heat flows out of me and collides
Into the glass, making a growing
Oval of condensation.

But it does little to stoke lyrical fires:
The moon above is refracted
In the cohesive spots suspended
Like swords above me.
