Based on the interaction you described, here's my analysis:
**Sincerity:** L's behavior and conversation topics seem somewhat insincere or calculated. She's making a point to mention her single status, her experience with dating apps, and her lack of interest in an older suitor. This could be a way to fish for information or gauge your interest.
**Intent:** L's intent appears to be at least partially flirtatious. By asking about your age, where you live, and complimenting your attitude, she's showing interest in getting to know you better. The fact that she wore a lot of makeup before your shift suggests she might have been trying to make a good impression.
**True Meaning:** Behind L's conversation, her true meaning might be to assess whether there's a romantic connection between the two of you. By sharing her dating app experiences, she might be hinting at her availability or seeking common ground. Her questions about you could be a way to determine if you're a potential match.
**Sentiment:** The sentiment of the conversation is friendly and casual, but with an undercurrent of flirtation. L's tone is likely playful and engaging, as she's trying to build a connection with you.
Some possible explanations for L's behavior include:
* She might be interested in you romantically and is trying to gauge your interest.
* She's trying to build a friendship or alliance with you, and her questions are a way to establish common ground.
* She's simply a social person who enjoys talking to others and doesn't have any ulterior motives.
Keep in mind that these are just observations based on a single interaction. You might need more conversations or interactions to get a better sense of L's true intentions.
