Stranger becomes friend or foe?

It was on one fine day, or one of those days when I missed my cab again. I got into a Volvo bus, standing, trying to finish my furity-breakfast doing the balancing act, when I over-heard the person standing next to me. He was a middle-aged man, early thirties I think, I’m not very good at guessing game. It was evident from his conversation that he was very much naïve to the city or atleast B’lore traffic. During the peak 10 o’clock office hour’s traffic, he was assuring someone on the phone, that he would reach Whitefield from Domlur in about 10minutes!! My heart leapt out to him and also the other person waiting for him and so I told him that it will not be feasible to reach that soon. He just enquired about the number of stops and roughly how long will it take and I answered his queries politely, all the while finishing the grapes by myself.
Later we just got into a typical introductory conversation of where from, what you do etc,. He was from Goa, not dressed in a bright flowery shirt or straw hat. Not an IT guy, for a change. He started asking me about my work, damn! My roller-coaster career with a shift from Biotechnology to IT industry, the dreadful question and then the job satisfaction part. I ponder over his questions, wondering how life has become, or I had let it happen to me.
Time flew by as we chatted for a little longer and then he popped the popular question of, “Are you on FB?” with my jaw dropped down, I blurt out frankly that I didn’t expect him to be on FB. I gave him my email id unaware of what it got me later. I reached my stop and we parted after exchanging pleasantries and not before providing him sufficient navigator information.
The day after, I see an email with a not so familiar name, but an eye-popping subject, “…from ITPL bus”. Now that was quick. After much dilemma I open the mail to see some phone number and about keeping in touch. Sigh! Bekitha? After having some internal conflicts, I sent a polite reply which doesn’t make a concrete promise of keeping in touch. But then I’m left with so many questions - too many to pen down, too many for me to handle. I feel like a kid refusing to grow up and wish I could go back to my cocoon sheltered by my parents.
But one of the many questions that still keep haunting me till date is - who else got my email id??
