She is just walking with Ian to the next bus stop. They are classmates and she just started vaping, but he smokes for a while now. She were vaping to the bus stop and he was smoking an cigarette. Suddenly he asked her "I have a new vape. Do you want to taste it?". She couldn't say no, so she takes his vape and takes a breath. She says "mhm, yes, it's good". They continued walking and talking.
