What is a secret that someone has told you and you’re not allowed to tell anyone but you’re going to tell redditors because no one will ever find out it was you that blabbed?

My wife once told me that she always has to buy shoes bigger that she needs because she has such small feet that it is really hard for her to find shoes that fit properly which aren’t kids shoes. She asked me not to tell anyone, but I think Reddit is a safe enough forum to not let this secret get beyond this website.
