My wording was maybe a little strong, I did try and clarify a bit in another comment below but, I was maybe a little bit unclear and think I might not have fully understood the point you were making. I admit, I did take it as juniors should just shut up, which i admit probably wasn't the most good faith way to interpret it.

I agree there's a difference between the kind of question like the one above vs. something like 'Why isn't there a check in there before unpacking a record?'

The first question is basically 'Teach me stuff I should know' the second is more along the lines of 'Why do we do it this way?'

And there does come a limit, if after a month they're still asking the same questions, not really seeming to have learned anything, it's probably not going to change.

I dunno, really I guess it usually comes down to the person and I hate to say it but, how annoying I find the questions and the person's behaviour.
