I sense that i appear to be rather 'mysterious' to some ppl... because oftentimes i look like i'm pensive, then in the end i don't even utter a word. then usually ppl get a lil bit concerned and will instead ask.... so are you ok? and usually ppl would in turn be at a loss as to what to say to me... and some ppl are seemingly baffled. i wonder if my boss is one of them... cos i'm not chatty like some colleagues and so during chance meetings after lunch on way back to office etc sometimes work is still discussed for lack of better conversation topics. hmm in fact, work issues almost always manage to find their way into lunch conversation generally... but guess that's not very unusual at all
