Every Australian knows the rule: if a tradie says "she'll be right" it means one of two things. Either everything is genuinely fine, or your house is about to fall down and he's already in his ute driving away. There is no middle ground.
@Daojoan The tense is very important. It's "she _wiill be_ right”, not “she is currently right”.
It's also important that we not get into how soon she will be right. At some point. Eventually. After you cease worrying about it.
The main thing is that it is inconvenient for you to be concerned, and you must shut up and relax.
