Have had this question popping up a fair amount recently and haven't been able to fully get my head around it.

Some background is that I am constantly joking around with friends and it has been slipping into my work too. It just seems to feel good to do it but it also looks like it is just a comforting aspect of interacting with people and the hard pill to swallow is being more stoic and distant because it gives people little to fuck with and they will then know you are all business. People at work seem to let it slide more and more the more I do it. Have been retaining myself a lot through never DEERing but I am unsure of holding on further into just letting laughter be enjoyed by others. It has fucked up previous workplace relations and I am starting to think its the only way.

Any advice on this? Also any books or links people recommend?
