When we went to Venice last year we got lost one evening and ended up at this festival on a square. Lots of Italians, eating sausages and drinking vino out of giant plastic Evian bottles. There was one couple, they must have been around 70, dancing to every single song. They were wearing their Sunday best and I bet you they have been going to the exact same festival for all their lives, dancing together. You can see them in this video, spinning around.
I thought they were amazing. I wanted my new husband to grab me and take me for a perfect dance too. Sadly I only had 9 toenails at the time and couldn't move much and he was busy anyway sourcing more Evian-bottled vino. Maybe when we're 70 we'll enroll in a salsa class.
