As amusing events...:
When I was 15 years old I started playing Airsoft, as in my group we were all minors, we went to the mountains to play it. Some of my companions were setting up watchtowers and sandbags in what ended up being private property (it was not marked as well that everything was "undergrowth"). In the middle of one of the games, 2 police cars parked very close to us.
I and a few of us saw them and started to warn the others on the walkies. The fool of the group began to shout like crazy "The police! The police!...". These, who by then had not seen us, began to run and we obviously did the same xd. We grabbed our things and got into the woods as fast as possible. We stayed hidden in bushes until they got tired and left.
Another anecdote that I never forget was a party outing with the group. A friend's bicycle was stolen and the police were called. I was with others smoking joints when I saw that some were talking to 2 men. I approached and from the conversation they were having, they were policemen (incognito) who were already in the area (a typical night spot for places where there are always problems). One of them stared at me but didn't say anything about it, what's more, they told us where the thieves were probably and threw us a hint so that we could give them their "deserved", they literally said "You have 5 minutes to talk to them before let us come. " In the end, the bike appeared but there was no rowfight.(Since then I have not smoked outside the home xd).
As a stupid event as a child...: In elementary school (when I was 8 years old) I discovered blue cheese and brought a decent piece in a taper. At free time, when no one was there, I put it behind the blackboard (there was a new blackboard hanging overhead in front of the old one, but clinging to it, both were very large and heavy). The cheese was completely crushed and held between the 2 slices. I quickly went to wash my hands. After that, I really regretted it because it took more than 1 week to find out where the smell came from, besides that it was winter and we couldn't have the windows open so the class was well scented during all that time.
