My cousin lives in California. Because that is such a long distance from Philadelphia, it takes a long time to drive there. This distance makes it so hard to visit her, and I miss her very much. Our parents think it is too hard to drive across the country to see each other, so I miss my cousin very much.

Because of this, I only see my cousin once a year. I want to see her more often so we can watch movies together, but our parents say no!

What supporting details explain why it is difficult for the author to see his/her cousin?
