Laws of Conservation for Parents

All those physics courses were good for something right? BTW, check out the first video on this site, it is funny (the rest are not very exciting).

I have formulated several laws of conservation for our household:

• Conservation of good behavior - if one child is behaving, the other will act up. Also if one child has been behaving exceptionally well one day, the next day will be hell.
  
• Conservation of good eating - if one child is eating well, the other will refuse to eat
• Conservation of birthday parties - if one child has too many kids at their party, the other will have none (another post to come on poor Dova's birthday party - or lack thereof!)
