gzabetas, don't be too hard on yourself about having a bit of emotion to a memory. That doesn't mean you aren't detached - just that you have real feelings. You excused yourself and hid the blip of sadness which sounds like the right thing to do.
"Professional partners" is a great term. I hope you can continue to aim for that in your parentingand not be too hard on yourself when you find a few bumps along the path.
