President Mary McAleese has been hailed as the greatest saleswoman in the world for west Donegal and an Irish language school in Glencolmcille.
Mrs McAleese completes a week at the school tomorrow where she has been refreshing her knowledge of Irish with 150 other adult students, many from the US and countries such as Sweden, Germany and Britain.
It is the President's eighth successive year at the school, which is run by Irish culture centre Oideas Gael.
Centre co-ordinator Liam Ó Cuinneagain said yesterday: "We love having the President here and she loves it too. Wherever she goes in the world she gives Oideas and Glencolmcille a big plug if she gets the opportunity. She's a great salesperson - we couldn't have better."
Summer students at the school have included outgoing British ambassador Stewart Eldon.
Mrs McAleese gets no preferential treatment from her teacher Ray MacManais, who is also her biographer. She sits in a wooden chair in a class with 15 other students.
She rarely says a word of English during the day - not that she would be sent home if she did.
"That kind of penalty applied only to teenagers in the old days of summers in the Gaeltacht," said Mr Ó Cuinneagain.
