Me: what if Sirius had a twin brother named kidding?

My brother:

Me: NO LIKE REALLY think about it,
"Are you Sirius"
"No, I'm kidding"
"So wait, are you him or not?"
"Seriously, I'm Kidding"
OMG you could confuse someone so bad.

My brother:

Me: you're on restriction. No more Harry Potter.

My brother:

Me: NO I wasn't serious, I was only kidding!
