An effort by a group of people working together to solve a problem
Answer:
It was on a sunny evening, my parents were out of town for the weekend and I thought it was a good idea to invite some friends over and have a party.
The party started soon after with music blaring, enough liquor (even though we were not up to eighteen), and plenty of necking.
The night was going on really well as my crush Tabitha seemed very interested in me that evening. We were walking hand in hand and she laughed at all my lame jokes, perhaps she was tipsy.
My dad had a gun in his bedroom upstairs which he always kept locked. I did not put too much thought to it, but quite a number of teenagers were in my parents' room, doing what teenagers do best.
Suddenly I heard a loud bang, we all went upstairs quickly and saw Raphael lying in a pool of blood. It appeared that he was playing with the gun, perhaps not knowing it was loaded and mistakenly squeezed the trigger.
A once-happy party turned sour in the twinkling of an eye. All I wanted was for the poor lad to be safe. I called 911 and he was taken to ICU.
Answer:
