It's a damn good thing you don't have real guns, and if you do, you best learn your lesson quick. I suggest you take a firearm safety course, and refresh what you should already know. They are YOUR guns, meaning YOUR responsibility, PERIOD. If you were responsible with them this incident would not have happened. Quit blaming everything , and everyone else. An ADULT, takes resposibility for his/her actions. Children say it was their fault. Admit you fucked up, and be happy noone has been injured yet due to YOUR negligence.
I don't mean to rag on you, or preach, but unless you take resposibility for your actions, you will be considered a child among your adult peers. I hope you have learnt a lesson, and will endeavour to be a more responsible owner of firearms.
