not to start? what a stupid asshole. like he would appreciate a kid not his own walking around his room while on the phone with dad. why can't these idiots put themselves in our place just long enough to see our point? that jerk owes you an apology and one hell of a good day today-without him or his kid.

I would have started moaning and groaning with loud noises of ecstasy. She would have beat a hasty retreat. Then when DH turned and said "Was that neccessary?" I would say "Don't start..."

Have a talk to her later and tell her that she is not to walk in her room unless she is bleeding to death or the house is on fire. Explain how rude it is and how would she like you to walk into her room while talking to someone on the phone while she is trying to sleep.
