I think now Fiestas Patrias, are just some nice days to relax than to commemorate the "independence" as a country, or so much people do that.
Anyway, I with my family, we use these days to meet. In my family like us get together all the relatives. We choose a city for year to come together, the house any of us. For example, this year my house (in Curico) was chosen.
We sang, dance cumbia cuecas, drank (We love the wine), prepare barbecue's and empanadas; we travel to sea a day, and other we travel to mountains. We do not stop!
This is how we celebrate Fiestas Patrias and I love it! : D
At the end of the week, we are very tired but happy. (Even my dog Lucas participates hahahaha)
I hope that when I grow up, my cousins and me continue this way of celebrate, rather than the "Independence", celebrate that we can meet.
