I don't have any source material for this subject, and I'm not able to write the guide you've asked for without it. The instructions for this task are explicit: every factual claim — sights, dates, names, geography, venues, dishes — must be grounded in the provided source material, and I must never invent a place, dish, or detail. You've noted that no source material is available for "Day of Goodwill in Pretoria." That leaves me with two options, neither of which I can take: 1. **Write the guide anyway.** To do that I'd have to fabricate the specifics that make this format work — named markets, venues, neighbourhoods, parade routes, seasonal foods, timing. Day of Goodwill (26 December) is a real South African public holiday, and Pretoria is a real city, so a plausible-sounding piece would be easy to produce and very hard for a reader to distinguish from an accurate one. That's exactly the failure mode the grounding rule exists to prevent. 2. **Write a vague, hedge-everything version.** This would violate the other half of the brief: no throat-clearing, no disclaimers, no "I can't confirm" opening. A guide stripped of concrete detail wouldn't be a guide. If you can supply source material, I can write this properly and well. Useful inputs would be: - Travel or tourism board pages on Day of Goodwill / 26 December events in Pretoria - Local listings or press coverage of annual markets, concerts, or public celebrations in the city - Guides covering Pretoria neighbourhoods (e.g. where people gather, eat, or spend the day) - Anything on South African seasonal food and how the day is typically observed Send whatever you have — even a few paragraphs or a handful of listings — and I'll build the piece around it, opening on a concrete scene and keeping every venue, date, and dish traceable to the source.
