My highest claim to fame is that my sister once called to say that I was the coolest person she knew.
Years later, I reminded her fondly of this statement.
She feigned amnesia.
This plunged me into a day long identity crisis, which was only resolved by another phone call from her, where she restated the forgotten praise.
Crisis averted.
But just to be on the safe side, I wrote down the day and time of this confirmation.
In case of any future take backs.
