She likes to rub against the bathroom floor mat. Does anyone else's shelties do this?
Crouton does this too! When she was at my parent's house on vacation they couldn't figure out what was doing that to the bathmat and my dad meanly convinced my grandma it was a ghost. All until they caught her in the act.
Her only quirk is that she will stick her face in front of my face. I think because I always give her kisses on her face, now she demands them when she's happy. The extreme version is when I'm reading she will 1. knock the book out of my hands 2. stand on my lap and stick her face in front of my face 3. not go away until I kiss it or give her scratches. (Also works when I'm watching tv. This especially works as a tool to wake me up, and my dreams always end with me being suffocated by fur.)
