Marco.. what you did is not a mischieve.. it is a crime... at least in the place i come from... real sad what you did.. i would not be talking about it at all.. this is beyond embarassment.. it is a pointless crime.. as someone might have gotten sick... and it is actually worse than crime.. cause crime has intention of gain.. and it is bad enough.. but when someone does it for fun.. that makes it much worse... it is not funny or amusing at all
