How to say in Thai..

[MZurf]

"You need to take responsibility for your own actions"

Or is that whole concept foreign to Thai culture?

[starrdog]

คุณต้องรับผิดชอบในสิ่งที่คุณทำ - if you can't read Thai, copy this into Google translate and hit the Translate button. A speaker button should appear. Hit the speaker button and Google will read it for you.

If you need a useful transcription (just one of the many), then go to:

Paste to the "Enter Thai text here" box and click "Submit".

kun dtông ráp pìt chôp nai sìng têe kun tam

Was just watching the Western version of "My Sassy Girl" and here's the variation they used:

คุณต้องรับผิดชอบการกระทำของตัวเอง

kun dtông ráp pìt chôp gaan grà-tam kŏng dtua ayng (thanks KuhnBENQ)

[Johpa]

คุณต้องรับผิดชอบการกระทำของตัวเอง is a bit high sounding for normal conversation. Make it more casual with คุณต้องรับผิดชอบการทำของตัวเอง

Using the previous transliteration (thank you copy and paste) kun dtông ráp pìt chôp gaan tam kŏng dtua ayng

No, the concept of taking responsibility for your own actions is not foreign to Thai culture.

Anyone who has been here awhile, away from the tourist areas, would know that very well.
