Not done this for a while.
This is your chance to unburden yourself and tell the assembled throng about something that is on your mind - something that has been eating away at your very soul and has made you unhappy.
It could be fairly innocuous (example - I posted fresh dog shit through my neighbour's letter box), or something far more serious (example - I really like That's What Makes You Beautiful by One Direction)*.
(*Examples are for illustration purposes only and are not representative of personal experience. Sort of.)
Confess, my child...
