One ready-made excuse

Take this and vanish gracefully.

I am out for conference duty inside a lanyard-heavy networking habitat and one more notification may cause a dramatic weather event. Invoices, scope creep, and any so-called quick tweak can wait until I resurface. I will answer once I have finished fistfighting the timeline and won enough to type. If this is genuinely urgent, send one clear note through the agreed emergency channel. Do not improvise a sixth emergency just because mine looks entertaining.
