Here is something a bloke wrote a while back. Kind of sounds like something my mother used to talk about as she got older and less patient.

"Young men have strong passions, and tend to gratify them indiscriminately. Of the bodily desires, it is the sexual by which they are most swayed and in which they show absence of self-control.

They are changeable and fickle in their desires, which are violent while they last, but quickly over: their impulses are keen but not deep-rooted, and are like sick people's attacks of hunger and thirst.

They are hot-tempered, and quick-tempered, and apt to give way to their anger; bad temper often gets the better of them, for owing to their love of honour they cannot bear being slighted, and are indignant if they imagine themselves unfairly treated.

While they love honour, they love victory still more; for youth is eager for superiority over others, and victory is one form of this.

They love both more than they love money, which indeed they love very little, not having yet learnt what it means to be without it -- this is the point of Pittacus' remark about Amphiaraus.

They look at the good side rather than the bad, not having yet witnessed many instances of wickedness. They trust others readily, because they have not yet often been cheated.

They are sanguine; nature warms their blood as though with excess of wine; and besides that, they have as yet met with few disappointments.

Their lives are mainly spent not in memory but in expectation; for expectation refers to the future, memory to the past, and youth has a long future before it and a short past behind it: on the first day of one's life one has nothing at all to remember, and can only look forward.

They are easily cheated, owing to the sanguine disposition just mentioned.

Their hot tempers and hopeful dispositions make them more courageous than older men are; the hot temper prevents fear, and the hopeful disposition creates confidence; we cannot feel fear so long as we are feeling angry, and any expectation of good makes us confident.

They are shy, accepting the rules of society in which they have been trained, and not yet believing in any other standard of honour.

They have exalted notions, because they have not yet been humbled by life or learnt its necessary limitations; moreover, their hopeful disposition makes them think themselves equal to great things -- and that means having exalted notions.

They would always rather do noble deeds than useful ones: their lives are regulated more by moral feeling than by reasoning; and whereas reasoning leads us to choose what is useful, moral goodness leads us to choose what is noble.

They are fonder of their friends, intimates, and companions than older men are, because they like spending their days in the company of others, and have not yet come to value either their friends or anything else by their usefulness to themselves.

All their mistakes are in the direction of doing things excessively and vehemently. They disobey Chilon's precept by overdoing everything, they love too much and hate too much, and the same thing with everything else.

They think they know everything, and are always quite sure about it; this, in fact, is why they overdo everything.

If they do wrong to others, it is because they mean to insult them, not to do them actual harm.

They are ready to pity others, because they think every one an honest man, or anyhow better than he is: they judge their neighbour by their own harmless natures, and so cannot think he deserves to be treated in that way.

They are fond of fun and therefore witty, wit being well-bred insolence " the Bloke was Aristotle [Rhetoric II:12:1389a-b].
