Yeah G-EMMA, it's always good to stick your neck out and ask these questions. What have you got to lose?!
I often found when training and now that I'm still on relatively low hours, that the books and FIs don't teach you everything - far from it - and as I don't personally have a whole lot of different experiences to draw on when faced with new situations, I open my gob without hesitation. It also pays to ask questions on PPRUNE even when you think you know the answer. Sometimes you may look daft, sometimes not...
On the flip side, it's sad that some people take unsavoury delight in putting you down when you do that.

But there are some lovely, helpful people on here too
