An online learning platform had organized a free online English course. I thought this time I could fulfill my dream of learning English. So, I sent them an email requesting to get the chance . However, in replying an email they told me that the free online English course is closed now because they have already enlisted the students and also said that I should have sent that email earlier. Having seen it I was so upset that I thought my dream just got ruined.
