Not The Same

The suicide bomber only managed to kill one person when he blew himself up at the sidewalk café: the security guard who kept him from killing more.
The bomber exploded in the guard’s embrace, both dying at the same time.
Both shared something else in common: the same exact type of cell phone. Down to the ringtone.
The guard’s widow got the phone of the bomber, and the bomber’s widow got the phone of the guard.
Neither noticed the difference or ever charged the batteries on the bloody devices. They just sat on memorial shelves, occasionally taken down for dusting.
