As already stated:
He made a big deal when we got on that “Bet you’re going to tell all your friends you rode an elevator with LeBron James, huh!”
To which I replied (very confused as to why he said that) “Who is LeBron James? You? What do you do?”
Because I had never heard of him.
I’ve never watched an NBA game in my life. Nor any professional game of any sport.
I just don’t care. Nor do I care if he cared, although according to all my friends, he looked massively deflated.
I am sure you ruined his day.
(You didn’t ruin his day. He didn’t care.)
