OMG I know! That annoys me soo much.
It's like, I know my horse more than you do; puh-leaseee lol.
Once I was picking Lexi's hooves, this occured about a week or two ago, & this new girl at my barn, who's about 12 was like "be careful not to touch the frog! it can hurt them cuz its sensitive." I felt like saying, "No, REALLY?! You think I'd know about that by now!" LOL. :P Ughh that stuff annoys me.
Ride more, worry less.
