I am here in Britain for the summer school experience in Coventry and I really got impressed to see that some topics are universal. I have known through my linguistics courses in France that the body language could be, in some way, a national way to express ourselves. But sometimes some gesture will not convey the same message according to the country from which you are coming from. Just to give you an example, I met a girl from Czech Republic and we had this little talk about how to wish for luck. In France we cross the fingers and in her country they just do a fist and shake it.
