Common questions, common answers

No question are stupid, there are just people with different knowledge.
What is common sense for one isn't for everyone.

agree, but when someone ask question which is just not bigger challenging question it feels silly question.

True, it feel silly, but you can be stunned how some common knowlegde for you can be unclear in many's mind, and how some common sense for other is a totally new concept for you.

Don't take people from high because of that, it spoils the experience of learning.

thats right, its way to clear our concepts but questions should be asked from internet (which many already answered lots of questions) and because normally people becomes angry on intellectual questions.
