If that's what she considers a vacation, why not? You only rate a vacation if you can afford to go away somewhere? Single mothers don't deserve a break because they can't afford to take the kids to Disney, or France, or the moon?
School is important, but not the totality of life for kids. I don't care what anyone says, I am the parent and I decide when I will pull them out of school for something. I don't take a week a month or even every year, it is far more important to live life's experiences than tow(toe?)the line your entire life. Sorry but I don't see why "living large" once in a while with the kids has to be a "federal case".
You gotta shake it up once in a while and live life while you've got it. I took my 12 year old daughter
out of school for a week in 1996 for the best vacation of our lives, 6 mos. later she was killed in an accident. I thank God everyday that we got to live that vacation together and anyone who lets the "powers that be" rattle their cage should think this over very carefully. You don't always have as much time as you think you do so try and enjoy what you've got while you've got it.
I doubt if anyone ever looks back and says "Gee, ya know, I really wish we hadn't taken the kids out of school for a week for vacation. Those wonderful memories are a real waste of space. Who needs to destress and relax anyway?"
