Just as Ashlar has said, they are all very much the same, and as JV has said, just relax and be yourself. They will go over your petition as well, ensuring that all of the information is correct (spelling, address, age etc.) they will also re-read your petition to ensure that you understand all of the verbage on it. If you have any questions, that you can think of, please feel free to ask, it is a "get to know you" time and the more they get to know you, the more you get to know them. It puts everyone at ease with each other. With our lodge, we encourage your spouse or significant other to be there with you as well, if they have any questions, they should be welcome to ask, and the answers should be upfront and open. Good luck and enjoy.
