Are we as good as we think we are?

I have seen this from the other side as well, I'm on other forums in areas that I'm not experienced in

Yes this is good for the sole.

and I've occasionally got responses like
"Just add ABC to the XYZ"

Yes been there got that. However if you reply and say something like, "sorry I am very new to all this could you say exactly what ABC is". Or better yet "sorry but I have Googled ABC and it can be sevral things, which one do you mean exactly"
It is a little pantomime dance we all have to do to establish what level of help is needed. It is important to understand both the question and the level of answer required.

Story:-
Little girl asks her dad "Where did I come from", dad asks mum to explain, mum takes girl into a quite room and, having prepared for this day, takes out the books, diagrams and goes through the full facts of life works, including the video. Then she asks her, "and why did you want to know?"
"Oh", says the girl "my friend Jane comes from Birmingham, and I wanted to know where I came from."
