A quote from a very well-known and influential writer:

"Boys and girls are dressing alike. They love luxury, have contempt for authority, show disrespect for their elders and prefer to chatter than to exercise. Children are now tyrants and not the servants of their households. They no longer show respect when elders enter the room, they contradict their parents, chatter over the top of their elders, gobble their food at the table, cross their legs, and tyrannise their teachers."

Socrates, 467-400BC

It seems the more things change, the more they stay the same...
