I'm very happy that today is the first day of summer vacation! And I'm enjoying the summer vacation.(except my mom said "Study, study, study!") I'm very happy! Because I can study that I want to.

And I'm enjoying the summer vacation but my Mom keeps on saying "Study! Study! Study!"
I'm very happy because I can study whenever I want to.
