professional vs. personal

Here is where the working part of me just soars...then crashes.

I was invited to organize and even to chair a session of a local upcoming Foreign Languages Conference, and it is an honor to even be considered, let alone asked outright. This kind of opportunity is great for my CV and professionally gives me a great deal of status in the Department at work.

However, we come to the issue that I am a full-time stay-at-home mamacita who "moonlights", shall we say, as university professor. I would love to jump at such a wonderful opportunity but know that, in accepting such a position that my family will take the brunt of the sacrifice. However, it would only be organizing a session, not an entire conference, which is much easier.

Torn, yes, but honored. The right answer will come to me, and I have a little time to think about it.
