Except I only noticed ctrl - alt - F4 . : -S Just had to restart my machine as I could n't work out the right key - combo to get my screen back . I ' m such a retard at times . How are you ?

Question: Why did I not notice the right combination right away ?
Answer: I 'm not great at paying attention .The machine was distracting me .I was thinking about something else .I did n't care about it .
