Nichole's Summer Vacation
Every summer Nichole goes to the countryside for a month. She stays at her uncle's farm
which is located at a spectacular place and helps him. She works very hard but she likes it
because she loves to spend time with her cousin Macy.
Nichole and Macy always have a great time together. They climb trees, pick fruits and
flowers and go to the local lake. They love being outdoors as there are a variety of species
of birds and animals. They also love playing in the ruins of an old temple, which is very
dangerous, but they enjoy imagining that they are adventurers looking for some exciting
experience. Macy and Nichole come back home before dark and then get ready for dinner.
After dinner, they go out and feed the animals. Before they go to bed they watch TV for a
little bit or read books about thrilling adventures of Tin-Tin. They are always very tired at the
end of the day that is why they usually fall asleep watching TV or reading.
