This is only the second time that Shelby has jumped on the swivel chair in almost 4 years. The first time was so dramatic that she never felt the need to try again. The chair turned around(swiveled) as she jumped on it and it scarred her all of this time. The trauma of Sophie chasing her down has given her the courage to try again. This has been a one time occurrence. I hope that it won’t take another 4 years for this event to happen again. Sophie is one scary Scottie.
