The different replies to 'thank you'

When you say 'thank you' to someone in English he or she will reply, "You are welcome." or "The pleasure is mine." However in Malay, if you utter 'Terima kasih" which is the equivalent of 'Thank you" in English, the reply is "Sama-sama" (literally same, same which means I thank you too). In Chinese, the reply to 'Xie Xie" which means 'thank you' too will be 'bu yong ke qi' (literally 'don't act like a guest' which has this hidden message : "We are friends, aren't we? Helping you is my duty. If you thank me, you want me to treat like a guest."
