the culture/language barriers being referred to here remind of a story i was telling someone about the other day, when i was training as a divemastr i used to assist in open water courses, quite often i would tell a lady in the course who was constantly siking in the pool 'youre overweighed', which they would hear 'youre overwieght' and we allkknow the reaction to that one, but in the edn when i explain, we have a laugh and all is ok, so yes a dual responsibility on the talker and the listner
