Gogo, one the main characters, has a short-term memory loss (like Dory in Finding Nemo) and the other, Didi, was just lonely and old. Someone known as Godot, out of pity or sadism, would send someone to them everyday to make an appointment for the next day. And apparently these appointments were tho only thing that kept them from killing themselves.
Being an atheist, I couldn't relate to the characters. Maybe I could have done so when I still believed in God and a savior called Mahdi, but right now, I couldn't sympathize with them. In my eyes, they were just two miserable old men who needed help but couldn't get it. I would have helped them if I could, but didn't want to hear their story.
I'm glad to have read it anyway. I'm sure I can't forget about it whenever someone talks about the promised return of Mahdi or Jesus or Buddha or whoever.
