Watch out, we got a supergeek here! [lol see what I did there?]
Ughhhh I hate cocky people... actually have an ex-friend who thinks her poop don't stink and basically, even though I'm a better rider than her she was CONSTANTLY telling me what to do with my horse... eventually I let her ride him to show her what he's like and he got strong with her [like he always does if you don't micromanage him] and she was like "OMG YOUR HORSE IS EVIL KILL HIM HE BOLTED ON ME OMG OMG"... I was like, no, I can handle him just fine thanks. So can 6 other people I've let ride him [including a total beginner!].
She still thinks she's the best thing that happened to horses since Black Beauty was written, even though "her" horse is a mental OTTB she can't handle/won't ride, and never actually gets fed. Suffice it to say I am no longer in contact with her.
Your reaction at the ending of Halo 4?
