After few months, dad told mum that, indeed that girl was pregnant when she was getting married. She was about 3 months pregnant and got married due to that. Only after giving birth, that family members revealed the truth. Of course among Indian families, controversial news like this will spread out fast. My mum was shocked as hell. She asked me, "How did you know?" and all I did was a *hair flip and I said nothing. The rest is a history.
Sometimes you can see and understand certain things which other people cannot see and understand no matter how much you explain to them. That is the reason why I could sense that the girl is pregnant when nobody else did. That's the reason why I chose Psychology over anything in this world.
