The dilemma

You read Tuesday's message about six times. Best thing about their week. The first three you sent were not yours, and by now you have written forty that were. Scrolling back to check which was which, you notice their replies land inside a minute every time, the same easy polish, including the one at ten past three in the morning. Thursday is in two days.

Your options

1. Leave it. Thursday is the actual test.
2. Tell them the first three were the assistant, before Thursday.
3. Write them something now, no help, no polish.
