Are you still 14? When I was 14 there were situations where tear gas grenades were thrown in the city where I went to school (Amsterdam) in the context of squatter riots. I did my best to avoid these, never felt the need to play edge lord and join the mob, don a keffiyeh and shout inane phrases. I did do plenty of 'stupid' things but picking up live grenades was just too damn stupid. The Darwin Award was still decades away but had I known the term I'd have applied it to those who do such things whether they're 14 or 41. If you really need to get rid of the thing you at most kick it away - also risky - but best just to move away from it until it detonates. I knew that at 14 and I still know it. Didn't you? Don't you?
