There are infinite possibilities here, some less probable than others.

Some are pretty much just like ours, with a trivial decision making the difference.

Heinkel #1: If I’d known my day would turn out like this, I would have just had that extra cornetto at breakfast.

Heinkel #2: I did have that extra cornetto at breakfast.

Others, unfortunately, are both close to our own and far more sinister.
