I can usually tell a 'horse person' from the rest. always have been able to. How? There will either be cowboy boots, hats, big belt buckles, shirts with horses (or show dates) on it, be talking about their horse - or all of the above. I won't even lie growing up I was one of those people who thought horse people were... I don't want to say weird. But I will. So now that I have my own horses I go out of my way to tone down the 'horsey' because I know there are a lot of people put off by it or already have their ideas of the "crazy horse girls" in their heads. Most people are surprised to learn I own horses - I do wear the cowboy boots (So comfy!), but apparently other than that I don't look the type ;)
Also because I will also admit a lot of the horse girls at my college ARE snobs and are typically very judgemental. 80% of the time I hear them talking about horses they're bashing this person or that person or the judges at the latest show or this training method or this horse at their barn. It's very off putting. Maybe it's exclusive to my school - we're VERY agriculture centric and have an entire farm dedicated to learning and whatnot, big farming school - but I tend to avoid the horsey scene here.
