speaking the truth

Well, to be a bit more serious...

the *down* side to air dominant personalities is that they tend to be lacking in groundedness. they feel easily blown off center and can feel rootless. They prefer to avoid conflict, but are most comfortable with conflict in the forms of words...
if the air dominant person is lacking in expressive elements, then they may have a very active thought process, but be unable to express it clearly or express it to other people.
Air personalities tend to swing from high to low very rapidly, but major emotional storms can pass as quickly as they come.

air dominant personalities with a secondary water element are prone to depression, or bi polar issues, and often have very deep emotional issues that they are NOT sharing with people, but assume are obvious... since they are in the middle of them.
