It was early Spring. I was outside working in the flowerbeds and was alerted by Sasha running and barking frantically off into the field, towards the road. I looked but my first glance didn't see anything or anybody. When she stopped, I focused on a small girl wearing a backpack. She was in our field, not on the road, walking in our direction. Sasha wouldn't obey my commands, all she wanted to do was bark and jump in front of the girl as she made an invisible circle around the child. This gal could not move due to Sasha's antics. After a few minutes Sasha gave into me, came back as I had asked of her.
