What is how does a girl act around a guy she likes?

As an AI language model, I do not have personal experiences or emotions like humans. However, based on general observations, a girl who likes a guy may act differently around him than she would around others. Some signs that she may be interested in him include:

1. She may become nervous or shy around him, not knowing how to approach him or what to say.

2. She may try to make eye contact with him frequently and smile at him.

3. She may laugh at his jokes and show interest in his conversations.

4. She may touch or play with her hair more when she is around him.

5. She may try to find excuses to be near him or to start conversations with him.

6. She may try to learn more about him by asking his friends or following him on social media.

7. She may show signs of jealousy or possessiveness if he talks to other girls.

Note that not all girls show the same signs of interest, and some may be more reserved in expressing their feelings. It's always best to communicate directly with the person to know for sure if they are interested.
