My personal take on selective mutism
....A child being shy and a 'medical profession' trying to justify their highly paid salaries, and useless existence... .
If they swept the roads, rather than come up with more ludicrous definitions that are just human behavior,they would do a lot more good for society.
They just wouldn't have new BMW's to drive. Shame.
I get what you're saying. Well, either way, if it has a name, people are more willing to take it seriously. Especially teachers.
