I wear mine at work - mainly to drown out the *-spouting oxygen thieves that make up the RAF (Regiment) that happen to drift past me from time to time. I see it as a cost and time saving measure because if I didn't wear it I would have caused actual bodily harm to those wa**ers who make my p*ss boil, spouting utter w*nk within my earshot, and therefore beginning the long and protracted discipline cycle the Army has in place. Do I walk round with it on? No, as that would make me a bell-end. Do I use it at my desk to drown out the distractions? - of course. Does it make me look like a c*nt? yeah, probably. Do I care? - do I f*ck!
the iPod helps but I sometimes wish I could wear a blindfold so I didn't have to see the bell-ends!
