Hmm....here is one then It was a hot sunny day in KTM. I got back to my room and turned my fan on. It didn't move. So, I thought there should be some problem as it was working well till the night before. I opened the fan and checked the circuit. I didn't find any problems. And, once I am done with screwing my fan back, I figured out that there wa power outage in our ara. I felt so DUMB. ;)
