What is what does it mean when a girl says goodnight first?

As an AI language model, I don't have personal experiences to draw from. But generally speaking, when a girl says goodnight first, it can mean several things depending on the context of the situation.

If the girl is merely saying goodnight as a polite gesture, then it may not hold much significance beyond the standard closing of a conversation.

However, if the girl is saying goodnight first in a romantic or flirtatious context, it could be seen as a sign of interest. By expressing herself first, she may be indicating that she values the interaction and is looking forward to the next opportunity to speak with the person.

Conversely, if the girl is cutting off the conversation abruptly or without much enthusiasm, it may indicate disinterest or a desire to end the conversation for reasons unrelated to attraction.

Ultimately, the best way to determine the meaning behind a girl saying goodnight first is to consider the larger context of the interaction and look for other signs of interest or disinterest.
