Your mom recently got divorced with your father..well about 5 years ago..

And that same year she hooked up with Kirk hammett your favourite guitarist...and that hookup resulted in your 4 year old sister Ollie

On her fourth birthday Kirk found out she was his kid and wanted to meet her so you your mom and her went to his concert but obviously you weren't his kid so you didn't wanna be there

But your sister wanted you there...

So..you 3 stood backstage..as Kirk walked up to you
