Totally appreciated both of your reasons not to grow a yeard. However I get the feeling from reading your posts that a part of you really wants to go for it. When will you be this close again? Why not? If your wife respects you -- and you can explain that this is important to you, this shouldn't be a major obstacle. As for your introverted personality, don't let it be a stumbling block separating you from a potential accomplishment like this. There are some times when it is best to lie low, and other times when boldness is best!
