I should specify, by fairly docile I mean they don't usually toss out threat displays. You should go ahead and get used to those hairs, she might calm a bit and do it less after a while but if you ever surprise or irritate them they can have a buttjerk reaction.

Out of all the Ts I kept I only got threat displays from a few species(mostly from my G. rosea - she could be downright EVIL!). The charging could have been a feeding response, LPs always seem to be hungry! If you want a calmer, more handleable one you might look into picking up a sling and holding it regularly after it hits around 2 inches or so. You won't have to wait long, they're eating machines and can grow extremely quickly despite efforts to slow grow them. I only fed mine 2 roaches a week and they both broke 4 inches, nearing 5, in their first year(from 1/2 inch slings).

As to those urticating hairs, the longer you're exposed the more they seem to irritate you(at least in my case). After keeping tarantulas for many years I couldn't even change a water dish without breaking out in hives and ended up finding homes for all except a mature male I let live out his remaining few months with me(much to my discomfort - he was a crazy hair kicker).
