Good for you, working in a nursing home. Older people need good care and to be treated with respect when the time comes they can't manage in their own home. I hope you find satisfaction in your work. Good luck with your English studies the language must be so very different from Japanese, so it must be hard work for you to study, but once you understand it then there are many countries where it is spoken and many good films and music which are better when enjoyed in their original language.
