Seven years old

My daughter is seven years old today, and she wants to have a cake.  I bought a pink cake for her.  I'm eating dinner with my daughter at the restarunt restaurant.  My daughter likes to eat meat.  We're happy.

Happy birthday to your daughter.

我希望你的女儿生日快乐。 (I hope that makes sense.)
