One day, I was just sitting on my bed, and my little dog walked over to me and butted her head against my leg, that being her signal that she wanted pets, so I start rubbing and petting her head, and she was getting really into it, just pressing her head into my leg, and she just kept pressing harder and harder into my leg until she ended up doing a headstand and fell over onto my lap. She then just fell asleep there while I watched some netflix for a couple hours.
