I mean that's how I am, especially since I just got back to LA Fitness recently...the real gym rats/ "meatheads" I've met are so into what they're doing they don't have time to notice other people.
I don't really go out my way to make friends, which some people may misinterpret as aggression or cockyiness for whatever reason, but in reality I'm just fully concentrated on my lifts because I know how to breed results.... Not to mention I'm operating at such a high intensity(heavy weight / low reps) that my face is probably a default with my headphones on full blast.... but if someone comes and ask a question, ( normally, youngins) I fully respond to them in a clear, calm and concise manner....
