Hmmmmmmm(20..................)…

My niece came down for the summer, to help out in the Joplin MO area as a volunteer, anyway. She has been riding my 10 year old Arabian Dameer. And I have noticed that like when she goes to pick out Dameer's hooves Dameer randomly starts flicking her tail, she did it some when I was picking her hooves but not like now. When my niece goes to cinch her up she flicks her tail even more, you'll walk behind her and its like she's literally trying to hit you with her tail same as cinching and picking out her hooves. Stupid question but......Is she like doing to see if she can get away with it? Or is this her way of telling my niece to knock it off I don't like it? I know stupid question....I had to ask its been bothering me. Please if your gonna be rude and nasty or comment just to laugh, DON'T comment. Thanks in advance!
