Here is a good example: a woman didn't like what her reader told her about her chances for getting back with her ex, so she stabbed her and her daughter to death.
No, I am NOT saying all reconciliation-seekers are nutjobs. And obviously this woman had some issues other than the fact that she had an unhappy love life. (And obviously calling this woman a "nutjob" is a little mild.) But thwarted passion and obsession often bleed over into each other and make good bedfellows. This is an extreme case - but I see its milder cousins (and nieces and nephews) all the time. Reconciliation is nearly the most-frequently-requested type of work, and it's the type I most frequently decline. Otherwise sane, friendly, and rational people can act completely irrational when it comes to passion - throw in some drama and tragedy, add a little unrequited feeling, toss with the Bearer of Bad News - recipe for a nasty mixture indeed.
