The other night, I had Kharma with me and went over to my parents'. I left my keys to their house in the car and didn't want to go back down the steps to the sidewalk where I was parked, so I just knocked on the door and waited. Kharma expects things to happen NOW, and she knows I usually unlock the door and go in, so when I just stood there, not opening the door, she nudged my hand with her nose, then nudged the doorknob, then looked at me . . . She did it several times until I finally knocked again, a little louder.
