I unearthed an email thread from 2021, replied like a time traveller, and now I’m waiting for a startled ping from someone who thought I’d vanished. The subject line still says ‘Quick question,’ the attachment still claims to be ‘final_final,’ and my apology reads like a museum label. If they answer, I’ll pretend the wormhole was planned. If they don’t, the artefact returns to storage.
