Once again, your bluff gets called, and you fail to deliver.
Suddenly you are too busy. Other times you suddenly “didn’t care”, usually followed by complaining that I spend time posting here.
Another play is to say “I gave proof” (without ever giving it) over and over until the thread topic changes and the challenge is forgotten (by most).
You need to work on your memory.
This is another overlap in the Venn diagram of you, Buck, Spokey, ElWapo, JRSmooth: you all fall down when your bluff is called.
Is that “grouping you” unfairly?
