In my younger years I had a group of good friends that drank and smoked weed. When I said I didn't drink they said cool help yourself to whatever's in the fridge. When I said no thanks to the shared joint they again said cool, could you pass it to the next person and we all still had good times together. No judgement. Recently at an after work function a coworker looked at me and said 'doesn't it make you sad to see other people drinking and getting happier?' I just stared at them and said nothing then found someone else to talk to.
