This thread is like a grade school math class word problem.
If OP was 11 when the horse was purchased…
And if horse is now 19
And if horse was 17 at the time of purchase, and/or 17 as of two years ago (BTW, is anyone else amazed that OP can determine the exact age of an >15yo horse from teeth alone?)
And if OP can account for 4 or 5 years of the horse’s historical whereabouts
And if OP claims to be neither a kid nor a troll
Then how old is OP?
You may factor into your response that trolls may not age at the same rate as earnest advice-seeking equestrians.
OP, if you’re a real girl, what advice do you want? Surely you’ve had a look around this forum before you posted and realize that this is a place where descriptions of dangerous behavior by animals who could “kill you in a second” are more likely to be met with an Ice Cube lyric than a warm and fuzzy affirmation that what’s important is that you and your horse are “both one”. So if this is all earnest but the advice you’ve gotten so far is unsatisfactory, what are you looking for here?
