Called off work today.

Depends on what you do for a living, and the urgency of your job. For example, if you're the only doctor in town, then taking the day off for your hobby is a little remiss.

I own and operate a small commercial door company, and I've been know to take a day here and there to do some personal things that others might find frivolous, and I know that some of the people who work for me have done the same from time to time. But, no one's life is depending on installing, replacing, or repairing their door, or at least that hasn't happened yet. lol

Sounds to me like your personal time is pretty used up with family stuff, and that's far more important than any thing else. I wouldn't second guess myself if I were in your shoes, and especially if you have some pending vacation time built up. I'd say, enjoy the day and "git'er done".

...just don't let the boss figure out that he can get along without ya! lol
