Unfortunately, I won't be able to attend this event as I'm from the London area and am in school that day. As a youth, I just wanted to point out, (and not trying to be nit picky), that your use of the words "you don't have to be old to be wise", aren't very youth friendly or inviting- rather they are offensive.
That's just my thoughts, however if you're looking for youth we know that, youth recognize that. As a suggestion, just leave out that next time.
Just my thoughts.
