When someone says "the same to you," it is often in response to a positive or negative statement. It is a way of expressing the hope that whatever the other person said or wished for, it will also apply to the person saying "the same to you". However, there are other similar phrases that can be used instead of "the same to you." One option might be "likewise," which is an abbreviated way of saying "I feel the same way" or "I reciprocate those feelings." Another option is "you too," which reflects a similar sentiment of reciprocity. Additionally, "right back at you" or "you as well" convey the same general idea of returning a positive sentiment.
