1st Time Air Soft

I have no idea what is air soft is until my friend say to me that it is a game with a air gun, he said that your like in a war game if you play air soft, and he said that it is fun to play air soft, so he ask me to play air soft at first I don't want to play because it will hurt me but he forced me to play because he said that is fun to play so I play air soft. At first I'm so nervous the game start I don't know what to do I just keep running in the game I don't have any idea how to play that game. After we play we ate outside and we keep talking about air soft he said that the next time we play I can hit somebody.
