They are looking at and buying things, and they are not in the hotel.
What are the speakers doing?
A. buying holiday souvenirs
They are clearly doing more than just looking round, and there is no evidence
that they are just comparing prices. They have not yet organised for things to
be sent. They are staying in a hotel abroad and Mildred has a list of relatives
she wants to buy something for.
What is the relationship between the speakers?
Mildred refers to 'us' and Simon is clearly their son.
