Unknown numbers

Last night I received a SMS from an unknown number. The person said he had my number in his old phone but don't remember how he got it. He knows my name, I don't recognize his but I think "NUS" was familiar to him. The thing is, he is an oil rigger who works offshore and have been one for almost 2 years. I'm sure I don't know any off-shore oil rigger person. But it was (almost) the longest finding-out-who-is-the-person-of-the-number-in-my-phone SMS conversation I've ever had which ended with us having no idea who the other is or how the number came to be in his phone. It also ended with him saying "take care, good night, guess you have school tomorrow so you have to rest."

It was definitely weird and my intuition tells me to be careful.

There was this one other time this guy accidentally SMSed to the wrong number (my number) and we ended up chatting anyway through SMS for quite a few weeks/months. He was a bartender who did not seem to have a good temper at all though he was decent to me. He tried asking me out but I constantly refused. After a while we stopped contact completely.

The wonders of SMS. Sometimes I think my phone is an IRC chatroom all on its own, or some ulu-ulu corner shop where people accidentally come upon and decide to have breakfast/lunch/dinner there.
