She teases the exact thing she wants him to defend
A clean compliment can make her sound too available too soon. A tease gives her room to move.
She says his shirt is trying hard. She asks if he always looks at people like he is solving a case. She picks something he can answer, not something that shuts him down. The point is not to insult him. It is to see whether he can take the hit and send something back without getting awkward.
You can hear the difference after his reply. A flat jab dies there. A flirty one leaves her smiling into the next sentence.
Goodbye gets stretched because leaving would kill the tension too early
When someone wants to leave, the exit gets simple. Bag closed. Hug done. Door open.
A stretched goodbye has extra tasks attached, and most of them are invented on the spot. She checks her phone but does not walk. She remembers one more question. She gets halfway to the door, then turns back with a comment that could have been said earlier. Her friends may already be outside, watching through the glass.
She is not confessing anything. She is keeping the last few minutes from closing too neatly.
