Opinions

A second opinion may not be exactly what you're looking for. What for you is flawless and sublime might be unremarkable to those whose opinions matter to you. They might find the object of your opinions quaint, lackluster, or, worst of all, not worth commenting upon.

These things can be borne somewhat when the knowledge is yours alone. This is why you must carefully consider with whom you're going to share your likes and your dislikes. Or anything, really.

Take a good, long look before speaking.
