She sounds like she'll be an amazing horse for a beginner!
Some horses are just that: they could care less about some things.
My arab-cross could care less about despooking items, but freaks out when we're riding in the arena and the horses in the adjacent pasture move around.
Every horse has at least one thing that will not necessarily make them act crazy and freak, but at least get them a bit uneasy. Maybe tack and being ridden isn't her "uneasy" thing, but a fallen tree, tinsel, bells, measuring tape, etc. could be.
Good luck with her! She sounds like she'll be a great riding horse. C:
It's where I learned about working hard
And having a little was just enough
