"I need more cake for this!" Harry grumbled, reaching for the plate where one, lonely piece remained. Snape had never had a sweet tooth, but the bland sponge cake worked amazingly well with the "treacle tart" cream. Longingly he looked at the remains and was utterly surprised when half of it was put on his plate, while the teenager pulled the cake-plate towards himself and started to scrub off the congealed sugar, before polishing off his half. The Potion Master wanted to protest but found that he could not speak.
