1. Present simple tense: Used throughout (e.g., "You can often tell," "they usually maintain") to describe general truths and habits, which is appropriate for this type of question.
2. Modal verbs: "can" and "might" are used to express possibility and typical behavior, which adds nuance and naturalness to the answer.
3. Present participle as adverbial: "Leaning in slightly" is used at the beginning of a sentence to describe an action that indicates engagement, showing flexibility in sentence structure.
4. Relative clause: "which makes you feel like they’re genuinely involved in what you’re saying" adds detail and explanation, making the answer more complex and fluent.
