This happened when I was about 5 years old, just when I got to know what April fool's day meant. I so badly wanted to fool someone on that day, and somehow thought of a plan. On AF day, I got up early and was unusually very active (my plan was active though). At the planned time, I went to my mom and with tearful eyes told her that I had lost my earring. I was expecting a shock, a shout (for my carelessness), or atleast a sad reaction to the supposed mishap. But to my surprises, my mom didn't even show the slightest reaction to it. I again tried my luck by explaining to her that I really lost it, when she said "Never mind, your tiny silver earring must be worth just 10 Rs. " !!!! At that age, I never knew silver was not as expensive as gold!!! Then when I told them it was a prank (so carefully planned and flopped), there was a laugh riot at home. To this day, they tease me with this incident!
