Rooster on the windowsill

Bell jars and other vessels have been in my dreams lately. I seem to notice them all around me.
They're about holding onto something, maybe something precious, but probably something I need to let go of.
But I like them in my drawings, where I can isolate forms from the environment; saving them or saving all the rest of us.
Or perhaps this time the drawing really is just about that rooster on the windowsill, ready to crow.
