I also don't really want to compete when it comes to my hobbies, and hobbies have a way of bringing out the comparison junkies and gatekeepers. They find out you're into something and they just want to tell you how awesome and expensive their stuff is. Your smoker will never be the right one, your RC plane/copter/car will never be the toppest of tiers, your audio setup will never allow you to experience that record like theirs (which means 'you haven't really heard it'), and your gaming PC has the wrong thermal paste applied in the wrong shape so you have never experienced performance like theirs.
It's really obnoxious and while I'm sure I've missed a couple decent conversations I know I've dodged a lot more unsolicited drivel by just keeping the hobbies I do to relax for fun to myself.
