Marriage is made of things you'll like about your partner, things you don't like and things you hate about him/her.
Some things will change. Some, you'll learn how to live with. But a few things you will hate a lot, but you'll have to tolerate them.
And it takes time until you find out which one is which.

How stupid can a man get?

VERY MUCH. That's all I can answer.

Pride (Latin, superbia)

1. A feeling of pleasure and satisfaction that you get when you or someone connected to you have achieved something special
2. A feeling of respect for yourself :dignity: 2a. A feeling that you are better or more important than other people :arrogance:
3. A group of Lions (??)

According to Aristotle, the Greek philosopher, pride was a virtue, something that every man of respect would have and honor it above all:
“Now the man is thought to be proud who thinks himself worthy of great things, being worthy of them; for he who does so beyond his deserts is a fool, but no virtuous man is foolish or silly. The proud man, then, is the man we have described. For he who is worthy of little and thinks himself worthy of little is temperate, but not proud; for pride implies greatness, as beauty implies a goodsized body, and little people may be neat and well-proportioned but cannot be beautiful.
Pride, then, seems to be a sort of crown of the virtues; for it makes them greater, and it is not found without them. Therefore it is hard to be truly proud; for it is impossible without nobility and goodness of character.”

Modern life, thou shows that things are not as they used to be. Pride is one of the Seven Deadly Sins. It is considered the original and most serious sin, from which the others arise. It is the Sin commited by Lucifer who wanted to become like God himself, it is Adam’s and Eve’s Sin who, convinced by the serpent, thought God wanted to be superior to them.
In ‘mortal terms’, Pride is when you really believes you are better than the others, and you either show everyone how better you are or you ‘respect’ their inferiority because they’re not to be blamed for not being great like you are. We usually do both, sometimes just helping out, being nice and teaching what we know, and other times we crush those who someway cross our way and piss us off.
Well, each of us carries our share of pride, some way more than others. In the end, we all want to be better at something, don’t we?
In Dante’s Divine Comedy, the Proud go to purgatory, where they are punished by being forced to carry a heavy stone in their back, which forces them to walk curved and look down. The pavement is carved with many examples of pride and humility, so they can learn while they walk.
