Nah, I keep to myself- but am outgoing & friendly if someone approaches me or asks me to spot or work in on a bench...
At my previous gym I was practically stalked for a while by this guy who would talk incessantly about sport stats,etc in the locker-room while I was toweling off & coming in & out of the showers.
When I was taking a Martial Arts. course, I be changing, stepping into my jockstrap & putting the cup in, etc. & he'd be there "Do you know who's the most winning NHL coach of all time? We'll...". If he was a friend I wouldn't have cared but he seemed odd!
