got approached at the bus stop

I was melting under the sweltering heat at a bus stop on campus, waiting for my bus, when i felt that the person beside me was asking me a question.

It's not unusual to have members of the public asking students for directions, especially when it's their first time in nus.

So i wasn't surprised when the young guy sitting beside me asked me where the arts faculty was.

After giving him the directions to the arts faculty (which was to cross the road to the opposite bus stop and hop onto a shuttle bus), he didn't move a budge.

Although i wondered why he didn't proceed to the destination he had just asked me, i thought i should just mind my own business and try to think of ice cream to cool myself down.

Then he started asking me random questions like where i studied, what i wanted to work as.. etc etc. And i answered briefly to all his questions in a polite smiling manner.

Remembering that my parents used to ground me on how un-approachable i can be sometimes and that i should be more enthusiastic when meeting new people, i attempted to be nicer and asked a few questions about him since he was nice to ask me questions about myself.

Apparently, he's working in nus and it's his first day at work today. No wonder, he was asking me where the arts faculty is.

When we got up the bus, he wanted to save a seat for me, thinking that i was going to sit beside him, and perhaps to continue the conversation we left at the bus stop. But i just smiled politely at him and said bye, before proceeding to the back to sit alone. He looked a bit disappointed.

I don't know whether i may come across as an unsociable person, but i get a bit apprehensive when it comes to opening up too much to someone i've just met, let alone someone whom i've never met before.

Am i being too unfriendly or do you guys think the same way as i do?
