I would like to hear of anyone else's experience of characteristics of the bi-polar person who is very intelligent. A couple of friends and a relative have this. One common trait is they can call you but they are unavailable or leave the phone off the hook all the time. "Getting into religion". Saying inappropriate things about sex around children, even though they wouldn't do anything just the shock value. Becoming obsessed about other peoples lives or motives. These people I know are great to ask advice from. They can be the most charming funny person in the world, then change just when all is well.
