Winter isn’t complete unless there’s a cosy bonfire, especially when it’s conveniently lit outside your house. Something about a bonfire inspires conversation. You find yourself perfectly at ease talking to strangers.
Other side effects are drunken singing and boisterous merriment. People can be found dancing with complete abandon near bonfires. Of course there are those who hold hands and ignore all the lunatics dancing. It has a secret way of making you feel much younger than you are.
Plus it keeps you warm! It’s winter, guys!
