Important call during theory test

I am not a maniac of cell phones by any mean. I realize that usually people at our age are automatically associated with texting a million messages per minute. But I am just somebody else, I don"t close my world in the keyboard of my cell phone, I prefer to meet people and talk to them in person. I never talk much on the phone. When I have an issue to get over, I tend to meet people. Unfortunately, one of the most important exams in my life so far got interrupted by a phone call I had to answer. A theory test was the case. It was in the morning and I got an important telephone from my university which I just had to take. The examiner didn"t understand it and threw me out of the place. I had to take the theory test again . I never thought that despite my using of cell phones is so rare, I will encounter such things. Why doesn"t it ever happen to people who normally cannot live without the mobiles? I don"t get it. normally I don"t even use it. it just lies in my pocket. And had to call exactly during theory test. That is what I call bad luck, in the purest form. Wouldn"t you agree? Have you ever had such an experience in your life? if yes, describe it right here. Maybe we are going to have an interesting discussion right here? Greetings!
