"Well I mean, I guess, if you don't account for latency. There is a moment where the 5-minute timer is still going after the 3 minute timer has ended, in which case the hourglasses would not be perfectly aligned."
"Though I guess that isn't relevant, considering the answer never touches upon this. But I do have an issue with what it does say."
"Puzzles, in Professor Layton at least, usually come in three types. Math problems, logic puzzles, and tricky wording."
"This is a Math Problem with a Tricky Wording answer."
"It says that the girl only turns the timers when the sand in one of them has fallen to the bottom. It doesn't explicitly state that a timer can only be flipped when all the sand in that one timer has fallen to the bottom, but like, that's heavily implied."
"So, the answer should be the lowest common denominator, right? 15 minutes?"
"But no, a singular misplaced word changed the meaning of the puzzle, and it makes the answer into something that no-one would reasonably guess on their first try."
"Hey, here's a puzzle for you."
"There are four chickens. The first three are Tim Tommy, and Trish. What is the fourth chicken's name?"
"The fourth chicken's name is What."
"Do you see my problem with puzzles like this? They aren't designed to be solvable problems. They're designed to make you look like an idiot, even though they were the ones that had answers that no normal person would guess because they would take into account what you mean, as opposed to the literal exact words you say."
"I don't care what Professor Layton says, the answer is 15 minutes."
