A guy challenged his best friend to stay off the computer for 1 week. If she did, he would ask her out. She did. The days went by. She finally stayed off, not knowing the boy had pneumonia, and was becoming sicker. She went on his Fb. reading his quote, "I love you. You did it! You will forever be in my heart" Tears dripped down her eyes. The next day... "knock knock..."
I understand most of it, but what does the "knock knock" part mean? I don't get it. Can someone explain what the knocking means?
Answer on I don't understand this Facebook like?
That might mean that the person died of pneumonia
