She was bemoaning the fact that she had “decided” to be a lesbian. She was about 30 years old, 5 feet tall and had to weight 200 pounds. She had the look of a person who had always been that fat so I guess that a man had never considered her as a prospect. She probably figured that finding a girl friend was the only way for her to go.
Whatever, at that point in her life she was admitting that it had been her choice.
I think there are more than a few of those.... gay by default, because nobody else wants them.
