If you want to know the answer to your question, you will have to ask the question.
If you don't let them know what you need, how would they know what you need?
Although there are some things there are no answers for, not even on Google. You won't know unless you look it up.
You may think they know what you need but they don't unless you tell them what you need.
The answer could be right in front of you but unless you look for it, you will never see it.
If you don't know but you need to know then ASK someone so you will know.
There is nothing wrong with asking but if you don't ASK you will wish you would have asked when things go wrong.
No one knows everything but everyone knows that if you want to learn anything you need to ASK someone who knows the answers you need.
If you don't ASK you will never know. ASK so you can make an informed decision.
