i'm not really sure, but i suppose its only polite to stop and say hi and exchange a few words when you run into someone u dont see everyday

but it seems i only ever run into such ppl when i feel like keeping to myself. and when i do, i have to run into them one after another. like some prank from up above.

it helps that my windwalk abilities are nearly maxed. so most of the time they dont see me. but its like a permanent thing. and later when i want to be seen, no one can.
