Teacher's day fake out

This morning, in my nine AM class, a student arrived late, really late.  She is normally a strong student so I didn't feel she had slept in or any such thing.  Also, she came to class with a armful of flowers.

The words,  "Thank you" whispered, luckily, escaped before I could stop myself.  I tried to ignore the flowers and continue class, all the time thinking, 'today is Teacher's Day.'

At the end of class, a student gave me a 200ml bottle of orange juice.  The flowers were either for or from her boyfriend -yesterday was Rose Day, another triumph of Korean marketing.
