Your bloody bus driver will turn out to be the fool he is when it comes to teaching. He is no fool in his job as a bus driver, though.
But you are the fool who suggests that untrained native speakers can make better teachers than those with formal credentials.
Are you the bus driver who claims to be able to teach? OMG, I would refuse to sit in the bus you drive and to send my kids to any class you "teach".
Fools should not be tolerated in ESL. [edited]

You did it with LG and now you're doing it with me. I didn't say that untrained native speakers make better teachers than native speakers with formal credentials. Untrained native speakers will never ever be as good in some jobs[most] as native speakers with credentials. There's just not enough of the latter to go around. We have to get real.
