Know What You're Talking About!

“A little knowledge is a dangerous thing,” so make sure you know quite a bit about a subject before you spout off. If you're giving someone information, make sure it's the right information. Otherwise keep quiet! There is nothing more annoying than a “know-it-all” who knows nothing.
If you're unfamiliar with a topic, don't be afraid to say so and ask questions of people.
If they are impatient with you or act as thought they think you are stupid for asking, let them know in no uncertain terms that they are out of line. Their intolerance certainly tells you a lot about how toxic they are. So watch out for them! Their actions may have revealed that they are a person from whom you need to keep your distance.
