I completely disagree. communication via appearance starts from an early age. Young girls (less than 7 yrs old) try to look pretty. There is communication too between girls via appearance. boys don’t enter the picture until much later.
Remember the red and blue journalists attending China’s presidential address. The red coat journalist got the mic and spoke of unrelenting support. The blue coat journalist was so taken aback by this weird support she began to eye the person from top to bottom. Both were women. And were native Chinese working for American media companies. They communicate with looks.
