if you've been fat all your life people that KNOW you are gonna know you've had surgery- or think youre sick. and trust me when I tell you if your wife knows, her bff knows and her bff's husband knows.
this lady at my job had the bypass a year ago and thought nobody here knew. the rapid weight loss and forever present protein shakes gave her away, though.
the point is nobody cares! we spend our entire lives worried about what people are going to say/think when in reality people are focused on their own issues.
its a personal decision to either tell or not. my closest friends and fam know- i'll tell the rest after its done.....
