Well I think the parents are very brave, I wasn't much older when I came out all them years ago.
I was 16years old at the time, but only very gradual, I was ''boy mode'' during the week, then most weekends I would dress as female, but then when I was 18 and lost contact with most of my school ''friends'' I went fulltime. Over 12years till my transition was complete, I more or less got to know different people who never knew my past and only knew me as a girl, never as a guy.
What them parents did, well very quickly must have been a shock to everybody, I don't think Id be brave enough to do it that way.
But everybodys situation is different.
