Just draw

I packed a box with a couple of cactus ears. They are going to Milwaukee to live with my sister-in-law. In the last few days, all my drawings have cactus ears in them.
A friend asked me once how you know, when drawing, that you are drawing from your own sub-conscious self, or the collective unconscious or simply influenced by you exterior environment. I said you just have to trust.
But now I think it just doesn't matter.
