I emailed him and asked him about that once. He says that he intentionally draws characters that can’t be identified, because he wants his cartoons to be inclusive. I guess they could be either male or female if you accept that his characters just have no hair.
I’ve got to say that I’ve enjoyed having Echo speakers around the house and the things that they can do. I know Amazon may be listening in on me, but they’re bored to tears if they are! But I enjoy having the Echo speakers turn lights on & off around the house, set the Nest thermostat without having to get up, play music, answer questions, etc.
