Thoughts in the window

I grew a couple of centimeters today.. An owner to one of the horses the barn´s owner has in training came yesterday to see her horse. Its been a few weeks since she was last here and a lot of things have changed since, we have a new tackroom and are getting ready to start building some new stalls. When she wanted to get showed around, the barn owner put a hand on my shoulder and said " Sofia will do it, she is the hostess of these stables." that made me feel pretty good about myself...That would make anyone that has a dream about managing the stables of a big time reining trainer feel good. I gladly show people around the stables, and plan trail rides, halloween parties and all the other things Im planning for the stable. Its alot of fun and all the girls there are so friendly and fun to be around. all except one...sometimes I just feel like hitting her with a broom. She. Gets. To. My. Nerves. Its like as if she loves to bring people down when they are happy, to remind everyone that we have no right to be happy because in some countries people are starving! I really dont get her.. M, a 15 year old girl in the barn who is always there with her mother, has bad days quiet alot. Shes 15, I dont remember if I had a single awesome day when I was 15. You´re supposed to be grumpy and a pain in the butt then. M has an amazing sence of humour and we can all have so much fun with her, but yesterday she had one of her days, she was unhappy ( cant blame the girl, her best friend died in a car accident about two weeks ago) and just not very upbeat. While she was cleaning her horses stall she said " O I just hate cleaning stalls" and then Ms Party Pooper bitchy mrs P ( lets call her that) says " O you just hate everything dont you?! The only thing you like is yourself!! You are just so selfish!"
Im not always the brightest and dont always say the right things, but that is not something you say to a 15 year old who´s friend just passed away. Its just not a very smart move.
She has something bad to say about everything! When me and R talked about throwing a xmas dinner in the stable this winter and that everyone should help with cooking she said " I cant cook so Im not coming".. Duh..thats why we should all help dumdum...
Or she gives me a nice comment when I ride Grace " That reining that you are doing..how hard can it be? all you do is run in circles isnt it? you dont really ride you just sit and let the horse run as it wants" Those comments makes me want to take my rein, hit her horses ass with it so he runs of bucking and she flies off. yes.. Im a mean mean person when I want to be...
Or when Im sweaping the aisle singing she says " Its almost like you just fell in love.. you are so happy" and I answer " No no, Im just happy, this is how I am when Im happy".. Party Pooper " O my.. I bet you are a real pain in the ass when you are in love"
See what I mean? I really dont get this ladys problem, she´s around 40 and single...maybe thats her problem... The rest of us in the stable are pretty damn close by now to hit her with a broom next time she opens her mouth..
