For me it is my pets. No pets allowed in my sewing spaces, too many dangerous things for them to get into. I do get the occasional breach in security by one of my cats but they are quickly corralled and banished. As much as I love them and adore their company I can't have them in there when I am working. I do find it amusing when I hear my Yoshi chirping and trilling on the other side of the door and I see a paw feeling about under the door. I only allow myself water in a capped container. No food except the occasional bite size chocolate.
