Sam, it’s not too late, you still have a chance to live up to your word:
You said “Tell you what: If Trump does nothing, I will come back to this thread and say, “I’m a big weenie for trusting a Trump tweet when I should know better.””
You can still live up to your word. It’s an incredibly minor thing, but that you haven’t yet lived up to such a minor promise might just show something about your character. But you still have a chance, if your word is something that matters to you.
