Your first question: "Have you done this before?"
Their answer: "No."
Your second question: "Have you read any guides/watched any videos?" (essentially, "Have you done any homework?")
Their answer: "..."

I'm assuming their lack of response was because in their head they were already imagining your third question, which with that kind of lead-in probably sounded like "Well why should I be expected to carry someone who can't even be arsed to do their homework?!"

I'm certainly not trying to ride your ass or anything, I'm just saying it is very, very easy to misread intent when your voice has no tone or inflection in this particular medium. The shorter and sweeter you keep your questions, the less likely they are to be misinterpreted.
