this mess happened to me 2 months ago. i am a vietnamesse college student and is attending a uni which have both native and international students.

one day i was put in a mixed class and was seated next to an american girl. she was very kind toward everyone and want to know more about my country and wanted me to show her around. i said yes and start giving her a tour after class.

we walked through the town center and was exchanging details about ourselves. then she told me she is a vegan. i was kinda suprised because my stupid self from the past think the majority of western are carnivores.

i told her :"hey i don't eating lots of veggies is good for your health, where would you get the energy you need?"

she said: "dont worry, i never do any heavy lifting in my life or going out much. so this is fine.

me: "yeah, with all those zero protiens diet of yours, i wouldn't be shocked if you eats those veggies on a wheelchair someday."

i am saying it in a jokingly tone, thinking she might laugh.

turned out i was wrong. she slapped me, called me a 'degenerate scum' then walked away.

the next day i was called into the principal's office. her parents were there, accused me for 'verbally abuse and showing racism toward their daughter.'

i was shocked, i have no idea what it mean, i dont recall saying anything bad to her. and my punishment is a 2 weeks suspension.

turned out, vegatables and wheelchair is an offensive word when said like my 'joke'

TIFU because i don't know how English works.
