The queue beyond the chalk line

An original narrative about an invented community auction.

We had drawn a chalk line to show where bidders should stand. Within ten minutes, it had disappeared beneath a row of shoes. The auctioneer stood on a low wooden box, lifting each object high enough for the people at the back to see. A chipped jug looked briefly magnificent above his head, then ordinary again when he lowered it.

My grandmother wanted the little clock. She had inspected it twice and decided what she would pay. When it appeared, however, she kept both hands inside her coat pockets. The first bid came from a man beside the door. Another followed from somewhere behind us.

I nudged her elbow. She gave me a sideways look and shook her head almost imperceptibly. The auctioneer's voice quickened. Numbers bounced between the door and the back row, climbing past the amount she had named. Only then did she take her hands out, flatten her gloves against her knees and smile.

On the way home, I asked whether she was disappointed. She said that liking something did not require her to follow it wherever the price went. I had watched the clock rise through the numbers; she had watched for the point at which to let it go.

How does the writer show the grandmother remaining controlled during the auction?
