When all the shit went down earlier this year I was tempted to write him a "ha-ha-told-you-so"-type email or expose him publicly, but I never did. I reckon its ultimately not necessary, but can't help but wonder if he remembers me.
Of course he remembers! When a person loses large sums of money, it is natural to begin to analyze why this happened, and whether there were options to avoid it. In this case, you could become his lifeline, if he were not a fool. But life will always bring a lesson, and she will not choose the easier one to do it, it can be very hard lessons.
In addition, there is such a type of people who will never admit their mistake, moreover, he could accuse you, that you understanding the situation, but "couldn't explain to him how things really are." I also worked as a manager at various jobs, and I know how a boss knows how to arrange everything so that you will always be wrong, and there is no point in arguing with him because in the end he will still find a way to show you his superiority on this job.
