FASTING MONTH

During this month, everybody is tired, including me. Why? For those students who are fasting, of course they are tired, but how about me? Why?
When you are talking in front and didn't get any response from them, then you will feel tired. because this is one man show. You are the only one 'syok sendiri' in front there, where got fun one. The atmosphere is very dull. It makes me tired.
