I live in Switzerland and couldn’t agree more, I wouldn’t like living in a country with just one season. Every season has its perks!
From what you write Bulgaria sounds very similar to Switzerland. Except for the cost of living. Here it’s just unbelievably expensive!
It is very expensive in Switzerland! That is why I have been postponing to visit it until I become rich :D. Switzerland has amazing mountains and it will be just a loss to not see them in all seasons :)
