This is going to be a very long story, so bare with me, it gets better towards the end.
So some back story.
I'm[20M] a scout, and have been for 14 years. Scouts usually have national and international meetings.
Last summer, this was the case. It was a 2 country international meet, on my country, with about 1500 scouts, boys and girls, all above 18, since it was only for the oldest section.
The meet divided the 1500 into groups of 20-25 each, and for 3 of the 7 days of the week, each group would do a different activity, in a different region of one of the two countries.
I got placed on the isle of Ons, north of Spain, a natural reserve. We went there for 3 days to clean the beaches and enjoy the private island for our hard work.
So we get there, and its amazing. Its literally a paradise for us only.
