So many people especially students these days are so afraid of asking what does that mean or questions in general... It's quite sad and painful when the professor asks if everything is understood and then it's dead silence but a few minutes later you get classmates sending you messages with questions... I think people are too scared of being wrong or just appearing clueless to the society, even though I've quite often told them that you have to fail if you want to succeed and each failure gets you closer to success. But I guess they didn't understand what I meant and they didn't ask for explanation...
