Yeah when i was like 13-14 i never admitted to anyone but i was a very shy kid also. I only talked about it with like 3-4 irl friends. Now that im 18 with a job and am not shy anymore i openly admit playing it to people, hell even 5-6 people at my work play it (they are over 20 years old). I've never had anyone try to be a dick to me for playing it. You'll realize that nobody gives a shit what you do once you graduate high school.
