That's really rude.
How can u just say all this??
Difficulty is something that is relative to and varies from person to person. What u find basic may be something confusing for the one who is asking it. Maybe u are super intelligent, but that just doesn't mean that you can say such to someone, just because he/she asked something which u find hilarious. If know something then it's good, and so, u should be respectful towards what other person is asking.
