1. How is this 'stooping low' on your mom's part? If you need to be weighed, and your doctor decides that this is the best option for you, then until you are old enough to know better and override your mom's "authority" then you shouldn't complain.
2. Also, didn't you just start a thread about your fiance? If you are about to be married, then you should be old enough to make your own medical decisions.
3. If your 'fiance' was attacked, then why would you be forced to weigh yourself? I understand if you don't want to share medical details with the intraweb, but if you tell it/us/penguin about your daily life then I can't imagine your having too many inhibitions sharing medical facts with us.
