mine big female is exactly the same way. she couldnt care less what i do as long as im not touching her....and even then she just slowly walks away.I had two (male and female) that were around six inches or so, and neither of them were all that defensive. They didn't kick hair and it took alot to get them to go into a threat display. I actually really miss them. They were very cool tarantulas. From what I hear though, they were definitely not the norm for that species.
