how do i tell if my sister likes someone or not

It can be challenging to directly determine if someone has feelings for someone else, but there are some signs you can look out for that may indicate your sister's interest in someone. Here are some things to consider:

1. Body language: Observe if she acts differently around that person. Does she make more eye contact, smile often, or seem nervous?

2. Verbal cues: Listen to her conversations about the person in question. Does she bring them up frequently or speak in a positive manner about them?

3. Social media activity: Pay attention to her interactions with the person on social media. If she frequently likes, comments, or shares their posts, it might be a sign of interest.

4. Time spent together: Notice if she actively seeks opportunities to spend time with the person, such as scheduling outings or events together.

5. Personal appearance: Has she started paying more attention to her appearance when she knows she'll be around this person? This could be a sign of trying to impress someone.

6. Sharing emotions: If she starts confiding in you about her feelings, it may signal that she's interested. However, remember to respect her privacy, and don't pressure her to disclose anything she isn't comfortable discussing.

Remember that these signs are not definitive proof, and it's always best to communicate openly and honestly with your sister if you want to understand her feelings better.
