"Hey, Professor Lupin?"
"Yes Harry?"
"I have a question about werewolves. Considering you are one, I thought you would be the best person to ask."
"Of course Harry, what's your question?"
"Well, werewolves only transform during a full moon, right?"
"Correct."
"Why?"
"...Why?"
"Yes, why?"
"Well, it is a magical illness spread by being bitten by another werewolf that causes the victim to go through a painful transformation into a wolf-like creature every full moon."
"Yes... But why?"
"I'm not understanding the question."
"What causes them to transform?"
"The full mo-"
"I know that. What I'm asking is, ok well we can see the moon because the sun's light is reflecting off it."
"Yes."
"And the moon is always there, even if we can't see the whole thing."
"Yes..."
"So, why does the light have to bounce off the full moon to make someone transform?"
"It-"
"Why don't werewolves transform during the day in the sun's light?"
"Because-"
"And if it's because of the moon, not the light, then wouldn't a werewolf transform every night?"
"Well...It doesn't...It's because...Well...Umm..."
"Yes?"
"...Google it."
