I can somewhat relate to you. I went to a buddys house for his birthday bbq during the summer. I knew there was going to be drinking there but I went anyways, he's one of my best friends who I grew up with. I don't have a license therefore I'm not able to drive. They respect my choice and won't offer me booze, but as night came they all decided to go to a bar. This particular bar is my dads watering hole so I went with them in hopes in seeing the old man. I felt so uncomfortable and out of place there as everyone there was drunk. I was comfortable about not drinking, but still I felt and knew I didn't belong there. That's something I'll never do again. I have no good reason not one to be in a bar or any setting where the primary purpose of being there is drinking.
