Is it wrong that I was in a circle with about 6 people smoking?
No it isn't. Did you talk to any of them?
Not really, they always make stupid jokes.
As long as it was outdoors then it is okay for you to join such a giant smoking group like that. You don't want to endanger people's health indoors.
WTF. It's cold outside.
If you are going to smoke, it should be outdoors. If you are inside, you want to make sure you have permission from the person that owns the property to smoke inside.
