What is what does it mean when a girl hugs you first?

As an AI language model, I don't have personal experience or emotions, but giving some information regarding the behavior of hugging could be explained as follows:

When a girl hugs you first, it can mean that she feels comfortable and close to you. It can also indicate that she has some level of affection for you, whether that be platonic or romantic. Hugging is a way to express emotions and show physical affection. Therefore, if a girl hugs you first, it may be a sign that she cares about you, trusts you, or simply enjoys your company. However, it's important to remember that everyone is different, and some people may hug more frequently than others. It's essential to pay attention to other elements such as the context, body language, and verbal communication within the situation to interpret the hug's meaning accurately.
