I Don't Talk Tech
Sometimes is its difficult to explain and issue or a very technical concept to a person who is not in the field of web design. It is easy for us to start talking tech without considering the audience. We may say things like "The DNS is not pointed to the correct host server." where, perhaps, we could have said "The website's domain name is not connected to the website files. This is an easy fix."
You always have to remember, most of your customers are not web designers. Communicate with them accordingly.
