presente Compré el presente hoy para la persona mayor. Un presente es un shochu de la patata y éste es un sabor suave que es muy fácil beber. La persona mayor tiene el teached amablemente muchos cosas durante este año y la anchura de aficiones de otra manera que trabajo también extendido. Desde una persona mayor aparentemente gusta el alcohol, si le gusta, me alegro.

Present to coworker I purchased the present today for the senior. A present is a potato shochu, and this is a soft taste that it is very easy to drink. The senior has teached many things kindly during this year, and the width of hobbies other than work also spread. Since a senior seemingly likes alcohol, if he likes, I am glad.
