My friend's facebook status update, as follows
'Met an Indonesian bloke on an airplane who's listening word of choice wasn't 'OK' or 'I see' or 'aha' but rather 'Here we go'. He'd say it every 4 or 5 words I spoke with a huge, earnest grin.
Try it on a friend for 4 minutes and watch their head explode in a cloud of angst and confusion.'
I've told a few people in the office and got a limp reaction. Hopefully you will be more appreciative.
