unsuccessful job fairs but new friends part 1

So tuesday night i went home on the train with my sister to get a good night sleep and prepare for the job fairs near my home. My sister gets out of class late at night, and we pack and go to the train station on campus. On the bus going through the rail road parking lot we pass by ten suffolk policemen cars and policemen. Some crime must have been committed because there were 3 guys handcuffed and sitting in silent on the ground with their backs against a parked car. And across was another car with 2 guys standing outside of it talking to policemen.
Anyways we thought after being stuck behind this blockade we would miss our train. But we got there with enough time to purchase our tickets and make a new friend. As we walk away from the ticket booths this guy comes up to us and asks if we have change for a 20$ to put in the machine, so he would not get coins back. I didn't have any cash on me, so i said no, and told him to use a card instead. He said he didn't want to and my sister told him to exchange the coins at the station later when he gets off. He took her advise and we walked towards the platform.
As we stand there waiting for the train, the same guy approaches us and thanks us for before. I again apologize. He then out of the blue asks what our majors are. I thought of it a little strange to start a convo/pickup line along the lines of that. I answered, "business". and he turns to my sister and she goes "business". then he got all excited, and ignored my sisters question when she asked him back. He goes "I am a business minor, and I need to find a easy business class to graduate. I am a computer science major and I have a 4.0. I do not want to mess that average up taking a hard business class." Impressed I gave him some advise. More un-traditional he then asked for our email addresses, and then our names. The train comes and he tells us how he has a two hour commute back home. Only I didn't hear that my sister told me. He had a strong Indian accent it was difficult for me to understand everything he said. As we broad the train we went for the top deck and he sat at the bottom. I would of sat with him and continued our conversation but i had a lot of reading to get done in my hour ride home.
