We've probably all heard of the idea that 1+1=3. Synergy, right?
M and I can totally see how a good marriage relationship results in synergy. We get more done, we're happier, we can do stuff that neither of us can do alone. You might think this means that M and I should spend as much time together as possible so we can work our synergy mojo. Not so.
My kids have mastered disergy.
Married couples and siblings are two very different things. It is often better for either M or I to go somewhere else, ANYWHERE else, and take one of the children with us. Either of the kids by themselves can be downright enjoyable. But get them together?
Not an additive function.
