Wow Sharon, I have been asked many times to go scuba diving and the only thing that keeps me from doing it is an attack(that is a D attack
) . I wish I could be like your sister. I think that this attitude thing has to do a lot with our personalities. I am shy and hate to be in the spotlight; also I like structuted things, so spontaneous stuff does not make it for me.
But you are absolutely right; it is all about the attitude.
