Friends' departure

Two of my closest friends, Mehedi and Eimon who are also married couple, have left Bangladesh today. Mehedi is going to pursue Ph.D. in UIUC. I wish them every success in life. I went their house today morning to bid them goodbye. I was in a melancholy mood. Though, in this modern world we can easily keep in touch by emails and instant messaging, the thought that I will not be able to see them for quite a long time overwhelmed me. They were supportive to me all the time during our friendship. In many of my crises, they were beside me, they came forward and tried to help me out. I am grateful to them for many many things. We shared a very good intimate relation. I am certainly going to miss them in the coming days :-(
