hi, liz! how are things? today i wanted to tell you about what we do as a family when we travel. i hope you'll be interested. my family is me, my mom, my dad and my older brother(or sister ). every day we find something to do. for example, as soon as we arrive, then immediately go to the park. there we have fun, and take pictures.   the next day the whole family goes shopping, and after a long shopping we go swimming in the sea.yesterday we went to the water park. i finally learned how to swim properly. today we visited the museum, i really liked it.. and tomorrow we plan to go to the cinema for a new cartoon.
