An activity without an obvious finish

Text A: an original contemporary practice extract.

Our family exchanged photographs through a group chat during the holiday. After the first evening, there was always another picture to answer. I began checking it while other things waited because leaving a message unanswered felt like walking away while somebody was speaking. Yet the conversation did not have a moment when everyone reached a door together.

I told the family I would look through the pictures after dinner and might not reply to every one. My aunt said she often sent photographs when she had a spare minute and did not expect an immediate audience. The chat continued, but I stopped treating its continued existence as a task still unfinished. A message could be waiting without somebody necessarily waiting for me.

Text B: an original contemporary practice extract.

At the open jigsaw table in the community hall, I sat down intending to fit a few pieces before my bus. People came and went, but each newly joined section exposed another gap. Leaving seemed strange while the puzzle was visibly incomplete and somebody beside me was still searching.

I mentioned the bus to the volunteer. She said the table was designed for people to contribute briefly; no visitor had to remain until the last piece. I fitted one edge, thanked the person beside me and went. The unfinished puzzle was not evidence that my visit had failed. Its continuing gaps made room for another person’s contribution after mine had ended.
