sometimes the truth hurts people's feelings! If they spend 10 or 20 hours making something and it's total shit, don't tell them! If you tell them it's not good, they might fix it! Make sure you tell everyone everything they make is good, so that they never can never recognize when they're on the wrong track. Surely there can be no drawbacks to engaging in a positive-only, harmonious love-fest, free of criticism and negative sentiment.
