WHat you say is essentially what you said to us:

* You feel that that the situation could of been handled more maturely had she approached you directly and that you are open to discuss it.

* That you realize she's doing her job as a parent and appreciate that she's looking out for you.

* That you understand her concerns but this is something that you've made a personal choice in doing and you feel that you can handle it responsibly.

You'll probably have a more productive conversation...
