Lights off!

I am getting used to the new bike. Suffering from pain now and then. Yesterday I had to visit my college for no reason and I happen to return to the city to fix number plates to my vehicle. ( I was riding it without one for 3 days!). I was not used to the sounds arising from the vehicles yet. After entering the city limits, I took a right turn followed by a left turn....
A guy seemed to chase me all the way since the second turn blowing his horn violently.I was annoyed with it. I stared at him through the rear mirror. Suddenly, he accelerated to come near me! I was just furious with his action and I kept cruising through. He came near me and told, " Switch of your turning indicator light!!!!"

I turned around and told him " Sorry"

I switched it off and felt very embarassed for my stupid act. I felt sorry for myself for not getting accustomed to the vehicle sounds.........
