“I told you so.” Generally speaking, what is your reaction when someone tells you this in a situation where you were in the wrong?

I don't often hear that, even when I'm wrong, but if I do, I acknowledge my mistake.

The only one I know who would say that is my wife, but it is usually in jest and I just throw her a raspberry.

I'm fine if it's said to me in this manner:

I'll let you know if that ever happens.

I was too busy with vomiting to care.  When I visited the USA, I was told not to eat the breakfast pizza, which had cheese, egg, sausage for the toppings and gravy instead of tomato sauce.  I couldn't handle it at that time of the morning.

You sho did.
