Never trust squeaky clean. An important life lesson.
Yes, one should never trust squeaky clean. Why? It's because perfection doesn't exist. What we see as squeaky clean is actually just dirt hidden well. Also, one should never try to look squeaky clean. It's a big red flag for the shrewd to take notice of. Doesn't matter how clever you think you are, the shrewd and the observant will always see through that squeaky clean. Instead, what you should do is to put some token dirt on you so that you avoid raising a red flag. Doing so will not just calm down suspicion but also lower envy. However, you must make sure that the dirt is nothing significant.
