Answer:
Yesterday I met Angélíca Morales. At the very moment I knew that we were going to be very good friends. Before I didn't know that you can start such a quick friendship. We have a lot of things in very close proximity to my house, in an apartment that I want to sell. We talked for several hours about our plans and dreams. Her family is from Guatemala and they came to visit her recently. She showed them all the city and the tourist places. They liked everything very much and hope to be able to return soon.
