Well I could give my opinion but it might not be any more valid than what you have already figured out. Here's a real life example:
I was in a pub (bar) somewhere far from where I live, alone, a bit insecure, so I brought with me a book just in case I couldn't cope socially. I bought myself a beer, sat down at a big table and looked around me. There were a few people dotted around including someone who looked a bit "shady", a gothic looking guy with a mop of jet black hair, on his own sharing the same table as me. From my peripheral vision I could see that he was staring at me, it freaked me out so I opened the book and started reading it in between sips of beer, all the time noticing that gothic floppy black haired stary guy was still staring at me. After a while, I looked up and his intense stare met me eye to eye, then he said "That's a great book ...if you can make it past the first 100 pages!" He was exactly right, I was struggling through it and I agreed. Next thing I knew, we were in full conversation, some of his friends joined us and ...to my surprise, I had made a bunch of friends.
