I think maybe if Charisma had put a small intro paragraph to explain the reasoning behind it, we would've read it in a different light. I'm not a big fan of blurb before a sketch but maybe in certain circumstances it's needed.
As a comedy sketch, I thought it just right in length, but as a character piece it was too short and maybe it needed a change from state A (the opening conflict) to state B (the closing scene conflict or resolution for one or both characters - which is different to the opening conflict). Maybe.
