a friend at work invited me to a Halloween party at the end of October that he's having at his house. he said I could invite all the friends I want, but I don't have any expect the friends I have at work. should I just not go, or just invite a friend or two from work (that he would obviously identify as a fellow coworker)? I've also never been to a party (22). I don't if I'm just overthinking this or what.
