Another thing I wanted to mention recently was that I, for reasons beyond my control, had to sit in for a "Brachos Party" this past Shabbat. Now, I'm the youngest of my clan, and I don't often see children, so seeing a whole array of toddlers and young children in their own environment is, to me, ...similar to the experience of watching a group of guinea pigs interact with each other. Perhaps it says something about my being "too interested" in the opposite sex or gender relations, but one thing that caught my eye the most was some of the interactions between the boys and the girls. The two specimens I studied most closely were a pair of toddlers (a male Uzbek and a blond female with Swiss features) and a pair of children (both Uzbek-American).
The toddlers concerned me since the girl was only a month older than the boy yet she seemed to run circles around him intellectually (unfortunately, probably a sign of what their future statuses will be in relation to one another in society when they become adults). Though all-in-all, they seemed not to harbor any particular disposition towards each other, in fact they seemed to get on quite well. Not half as well, though, as the two Uzbek-American children (male: 6, female: 4). If I didn't know better I would think they were just a happily married, albeit very small, couple. The way their personalities complimented one another was uncanny, and even when one wronged the other to the point of causing tears, they were not able to, or perhaps did not want to, recall each others wrongs later on.
To me what these children seemed to be doing was enforcing a theory I had already had regarding the spousal compatibility of men and women, namely that any two people have the potential to live side by side in relative harmony. The only reason two people would not do so is because they are both concentrating their vision on unimportant and negligible differences between them, yet they overlook the vast amount of things they have in common with one another. And even if you grouped people with nothing in common (say, a Polish man and Ethiopian woman stranded on a desrted island), chances are they both manage to live in harmony and work for one anthers welfare.
