speaking their language

at the woodcraft shop...

me:  'and then this one has to be 120 mm...'

worker:  'we don't have mm...'

me:  'huh?!  of course, you do...'

i check his tape measure...  i go, 'there!  that's mm...'

worker:  ' that's centimeter!'

me:  'oh, just remove the zero from mm that would be centimeter...  120 mm is 12 centimeters...'

guy looks at me and i'm not really sure whether that's an expression of understanding on his face...  : }

uhm...  i think i have to revise my drawing and change all the 0.5's and 0.25's to 1/2 and 1/4...
