I have learned that paying attention when someone talks is really important regardless of how long he/she have been talking. You must really absorb every bit of information no matter how lengthy it is. You should not expect that queries after that will be entertained without any sarcasm. Maybe sarcasm depends on the attitude of the person you’re going to ask for some clarification. I guess it is really a stupid thing to ask when you have just been told what to do awhile ago. Lastly, I have learned there should be no room for panic attack. Panic just make things worst.
