Always be aware of your category of friends.
There’s a difference between your party friends, your college friends, your con friends, etc., etc. There’s a difference namely in how often you would hang out with said groups of friends.
Your party friends you may hang out with only at parties, but never outside of said environment; your con friends only at cons; college friends only in college settings; and you get the point >.> The main thing is that you don’t hang out with all your groups of friends as frequently as other groups.
Here’s the problem..
Since each group has its own settings you would hang out with them, some groups more ‘flexible’ than others, sometimes you may make the mistake of hanging out with these groups too often/not often enough. Besides the added stress, unnecessary confrontations, and general messy situations this will cause, you just DON’T want to bring your party friends with you to a business related social gathering; it reflects poorly on your character and you won’t get the job, just sayin’ ~.~
