Attitude No. = Birth no. + Month No.

The 7 Attitude. You don't get to know what they're thinking or feeling. They keep to themselves and are introspective. They must continue studying the quest of why they are here: The 7 Attitude asks the big questions.
They will reveal themselves slowly as they go. They can shut down and make you feel they are not remotely interested in what you are saying, but the joke is on you because they are the ultimate observers. They don't miss anything.
