49 David Lost His Mind?

David opened the black suitcase on the table and smiled broadly at the contents of the suitcase which he asked Lucy to send to his place without telling Lucy what was in it.

 David's type of smile like this he only shows when David sees one of several weapons which is on his list of favorite weapons.

 M416 Carbin, an automatic firearm which is a short and light version of the M16 assault rifle which only has single-shot and burst-shot modes.

 Single-shot is a mode where every time the trigger pulls only one bullet that comes out. Meanwhile, the burst-shot will launch three bullets for one pull on the trigger of the weapon on the shooter's index finger.

 David closed his black suitcase again and put it into a car he rented and drove the car somewhere.
