Script:

Emma: Hello, Jack. Nice to see you here. What are you doing?

Jack: Hi, Emma. I'm going through a long shopping list for my family picnic. We leave at 7 a.m. tomorrow. Are you buying groceries?

Emma: No, my family doesn’t do grocery shopping in supermarkets. We usually go to convenience stores instead. I'm buying some batteries and a flashlight.

Jack: Why?

Emma: These are for an emergency in case of a natural disaster.

Jack: Is there one coming?

Emma: No, but my family just wants to be prepared for the future.

Jack: In my family, we buy emergency supplies as soon as we see the news about an upcoming natural disaster.

Emma: You shouldn't wait until you hear a warning from the authority. Natural disasters can come suddenly and some can't be predicted like earthquakes.

Jack: That makes sense. I'll buy emergency supplies after I finish shopping for the picnic.

She is ___________ aimlessly around the shops to enjoy the hustle and bustle of city life.
