It was Valentine's Day week, and the Weasleys, Harry and Hermione were being given the grand tour of Percy and Audrey's new flat in London. The holiday had happened to fall on both a weekend and an outing to Hogsmeade, so Harry and Ron had met the girls in the wizarding village again before escorting them back by train into the city, to bunk overnight at the Burrow before coming to this, a snowy Sunday visit.
