Your brain decides to throw a tantrum in the middle of a happy moment because it’s got a grudge.

I was about to get a promotion and then I remembered I got fired last year.

I was about to eat my favorite pizza and then I remembered I had a root canal.

I was about to win the game and then my brain reminded me I got bullied in 2009.
