Counterfactual snackbars.

Concluding this, the theory states that both the counterfactual statements ``If A had not been open, we would not have seen the man with the hamburger'' and ``If A had not been open, B would have been open'' should not be accepted.

If after working this out I still have any such thing as intuitions or opinions about these counterfactuals, then I very much agree with this result: When constructing a possible world in which A had not been open, to keep our thoughts consistent, we do not necessarily need to remove the hamburger-man and we do not necessarily need to open the other snackbar.

All we need to do, is do at least one of these things.

There must be 50 ways to leave your lover."
