If one of your humans is engaged in some activity, and the other is idle, stay with the busy one. When supervising cooking, sit just behind the left heel of the cook. You cannot be seen and thereby stand a better chance of being stepped on and then picked up and comforted. When human is working at computer, jump up on desk, walk across keyboard, bat at mouse pointer on screen, and then lay in human's lap across arms, hampering typing in progress. This will help their coordination skills.
Humans love the feel of kitty litter between their toes.
Do not come out for three to four hours under any circumstances. Once you do come out, the humans will cover you with love and kisses, and you probably will get a treat. Humans love this, so do it often. And don't forget the guests. I don't have one.
