Has hell frozen over?

Either two nemesis have called a truce, or it's the end of days, when the lion lays down with the lamb. Much to my surprise, Allegra and Dexter both snuck on the bed when I laid down for a quick nap to relieve the tedium of grading papers. I don't know what surprises me more, Dexter getting on the bed (which he hardly does when there is someone on it), Dexter getting on the bed with Allegra on it (heaven forbid!) or that Dante wasn't anywhere to be found.
