<human>: So this didn't happened today, it happened a year ago during Carnival.

A little background: It was Carnival and here in Portugal as a student you get 3 days off school (Monday to Wednesday), so a friend of mine invited me and 2 other friends to go his grandparents house in a little countryside town called Reguengos during the 5 days of "vacations".

In the beggining of the 2nd or the 3rd nigth we headed up to the terrace ( this a big house and the terrace was like a 3rd or even a 4th floor) we started to drink vodka with cola and smoking weed, after 5mins we were high and getting drunk. It was windy and one of my friends saw the anemometer (you know that thing that measures wind with 3 little spoon like things) rotating violently and so he decided to slap that thing in the wrong direction, that shit broke and landed a couple of meters ahead in the roof( the roof had a straigth and narrow wall separating the tiles) so my friend went there to catch the little thing, and I decided to do the same, I put my feet on the roof (dont forget I was fucking high, and almost drunk , a fun combination when you are not on the roof) and sliped, lucky me one of my friends was in front of me and grabbed my arm, I think I grabed on to the roof but I can't really remember. If it wasn't for him I wouldn't be here telling you guys this story.

Can you provide a brief overview of the text?
