Lesson1:

As Ted Mosby says nothing good happens after 2 am. For me it is like nothing good happens after you are drunk. Please keep the mobile phone at a distance or get ready for the impending catastrophe.

Lesson2:

Never read a Hindu newspaper when you are in a crowded bus. People may misconstrue, that you are too smart or intelligent.

Lesson3:

This is what your parents would have said when you were young. Never take sweets or other delicacies from strangers. Should have remembered what amma told when I was 5.

Lesson4:

Never tell your CAT score to anyone. People may brand you with that to such an extent that you would feel like jumping from 5th floor.

Lesson5:

Never discuss philosophy with someone whom you don't know, even if you are too good in it. Satre, Nietzsche, Russel whoever you know or have read wont help. As the saying goes 'never argue with idiots as they may drag you down to their level and then beat you with their experience'
