Shopping trolleys

The she boss took me shopping tonight. Of course no one lets me go in with her but I stay on guard outside. It's pretty good as we go across my field on the way and way back so I can have a good run around.
I usually don't mind staying outside and the she boss ties me up by all the shiny metal. Tonight though there were lots of people taking the metal things out and bringing them back. They made a very scary noise and it felt like the she boss was a long time. I was so relieved when she came back. She saw I was very scared and told me how sorry she was. I don't think that will happen again
