"If you suddenly ran into your most recent ex, what would your first response be?"
It has been over two years, and even at the time the chain of events was a little fuzzy, so while I have a Big, Monster, Official Ex, there is also a sort of Pseudo-Ex that immediately followed.
For the PE: There would be a huge amount of obscenities, and possibly some violence. I would use words like abandon, and coward, and PE would say something with liar. Then we would hug.
If, however, I ever, ever run in to BMOE again, I will turn to stone.
