“Humans… Hmm”

I don’t know what it is about me, but at times I feel overwhelmed by humans… That’s why I sometimes say, “Oh gosh humans… somebody please give me a dog… hmm."

“So why are you standing close to me?”
He stepped back, but continued shouting that he did not know me. I did not say anything, but continued with my purchase, keeping my wits about me.

He said, “Miss, can I please pay for this item, before you?”
I said, “No.”
“It is just one item?”
“I also have one item.” I said as I looked at him stunned.
