This girl does not strike me as being ugly but then, to each his own. Crazy? Now I can agree with that based upon what appears to be the case here. What's a 36 yr old doing with a 20 yr old (with obviously still developing coping mechanisms -- not unusual for that age) in the first place besides the obvious? Raises questions about Mr. McNair's judgment.
For those speculating on whether the wife knew, I read in the Tenneseean this weekend that the McNairs recently put their house up for sale. Couple that with the fact that McNair shared the condo with his friend and no attempt was made to hide this relationship and I think it's safe to say that the wife knew and she and Mr. McNair were already on the outs (whether occasioned by the affair or something prior).
