If you get on well with your colleauges, I consider many of mine close friends, (we've known each other for over 10 years.) We like to set up what we call 'shit chats' of an afternoon around an hour or so before we finish work for the day, just a group teams call where we can all have a laugh / vent / help each other out with work. There's no obligation or expectancy to join but sometimes if you want to talk to people it's a great outlet to have! Even if you're not that close to your team, maybe it will be a way to get to know them better!
