The hazards of pug ownership

I have to be very careful whenever I'm at my desktop computer. Within minutes of sitting in the chair, I have a "chair stopper" in the form of Winston resting his head on the wheeled arms of the chair. This requires me to be very careful when I decide to move the chair and give him advance notice. This despite the fact that there are two very comfy pug-friendly areas for him to lay on nearby.
