I have some really funny colleagues, a bit strange actually. It’s very hard for me to stay serious at work. Usually I manage, but sometimes I can’t. They have some weird ideas. For example, when I talk to one of them nicely or I am friendly, they somehow get the wrong idea, and most of them are female! 
I don’t talk a lot, but if I once in a while do have a chat with one of them, boy do they get carried away! I’ve never had colleagues like that before, hahaha. They are friendly, but they have rich imaginations, unbelievable.
Sometimes it really is difficult to remain serious. So what kind of work atmosphere do you have?
