(Some of the) Things I do not understand

I might as well go straight to the point, but then it would be unfair to my target.

Let's start with things I really don't have a clue about like chemistry; although I am certainly interested in the structure and behavior of matter, I just don't think in terms of atoms and molecules and I do have a problem with learning formulae.

Along with that goes physics. It might even reach the boundaries of ridiculous, because I know what is meant with force and the difference between push and pull but I keep mixing the things up - yes, in any language I at least read.

Another embarrassing thing is that I don't understand what men mean when they use codes, so if I am asked "Would you like to have a coffee together?" my answer would most likely be "Thanks, but I'd miss the 5:30 bus".

Now, being married, I feel relieved I don't have to care anymore about this.

I also don't understand envy.

Sure, there are people who have more advantages (and not always justified) than others, but I don't hate them and I wouldn't change place with them. I've got a satisfied  mind and even though there are things I wish in my life, they are pretty much depending on myself and self-improvement, so anybody else is just not responsible for my periodical pissed mood.

If there happen to be one person who's responsible for that, than I am avoiding him or her. As simple as that: I don't understand why people stick around  someone they could as well do without - if it's not strictly necessary as in case of  colleagues. That's not me. (Just picture me in a western setting saying "There is not enough room for the two of us in this town").
That said, the number of people I deeply dislike is very limited.

So, here I come, to the point I mentioned before.
What I DO NOT understand is men and motors. I could mention the two separated, but it wouldn't be fair to myself, because I have good men-friends and I understand them quite well (I don't always have to agree with them, of course) and I have a basic understanding of motors (just try to get a drivers license in Italy and you won't go around that!).
But men&motors it's just as puzzling as man-on-the-moon.

There is some reason why I am mentioning this. Recently I noticed that a father in Carlotta's pre-school is coming to pick up his child with his sporty car. Nothing against that, if he wasn't driving at the same speed he's driving on a town street with speed limit 30 (which means he's driving 40mph).

Does he want to be noticed?Well, he managed to be.
Let me be mean: when I see a man driving like that, my first thought is that he has to compensate some lack.
I am really sorry I didn't talk to him (yet): I am always trying to get out of his way not to get hit...

But what pisses me most is that he is doing his miserable manly show in a school's parking lot, during pick-up time, when moms and kids are around.
There is a racing circuit not too far, doesn't he want to try it there?

...of course the list of things I don't understand is much longer and includes other important issues, but as for now I'll stay focused on that and try to talk friendly to this guy - something tells me that people like this aren't open to criticism but I might be wrong.
