Three consecutive troubles

It was not so good day today. I performed three experiments, and all of them showed me melancholy results. I should spend a day to solve them all. Although it was not so troublesome if they come to me by alone, the case when they come simultaneously bothers me. Anyway, I know that I can feel happy after the recovery of these troubles. Actually I had a premonition of coming the third problem after meeting with the second trouble.       I      don't     know      why     I     am    so    tired!
