I was going to say you're lucky to have such a well trained dog but that's not luck. You were smart to train her, now you can enjoy her company and you can lay back knowing she won't do any damage to anything or anyone.
How many dog owners I've seen who couldn't care less about training their dogs, then when the dog took over and destroyed everything, they got rid of the dog.
I'm always saying dogs should be owned by those who are willing to train them.
She's nice by the way.
