A secretary is an administrative assistant in business office administration.
The executive secretary (sometimes called executive assistant, administrative assistant or associate) has myriad administrative duties. Traditionally, these duties were mostly related to correspondence, such as the typing out of letters. The advent of word processing has significantly reduced the time that such duties require, with the result that many new tasks have come under the purview of the secretary.
A nice shot of Aum looking pretty cute wading around in the swimming pool. Of course she is wearing too many clothes for going swimming. But that is Thai style, although Aum is one of the models who likes to show more skin than what the monitors of proper behaviour approve of. Still, she has a bikini on but then a cover-up over it. So we don't get to see how very cute her swimming suit might be and the little boutique where she bought it might be sad nobody sees it, while the designer name label gets no exposure.
