I confess to… hooking up with you the for first time because I mistook you for your brother.
I confess to… tagging my twin in a photo of me cheating on my girlfriend… My twin got dumped, I got engaged.
I confess to… getting off school early after telling my teacher that my granddad had died. He had died, two years earlier.
I confess to… quickly eating all my favourite colour sweets and pretending there were none in the packet.
