"I remember you."
Translation:Tôi nhớ bạn.
The way I look at it, "nhớ" just means "remember". In English, we say we miss something or someone because it's not part of our lives anymore. It's lacking in our lives. In Vietnamese, they instead say they remember something or someone from before. Recalling fond memories.
So literally speaking, "tôi nhớ bạn" = "I remember you" and that can be true. However, in a different context "tôi nhớ bạn" can mean "I miss you". Therefore, both answers ("miss" and "remember") should both be accepted since there is no context.
Isn't that beautiful though? I feel that "tôi nhớ bạn" has a more positive tone than "I miss you" =)
