Let’s break it down:

1. Identifying the Verb: The main verb in the sentence is played, which tells us what action is taking place.
2. Finding the Subject: To find the subject, we ask who is doing the action of the verb. Here, we ask who played? The answer is Millie.
3. Understanding the Predicate: The rest of the sentence ‘at her friend’s house’ provides additional information about where Millie played, but it does not affect who is performing the action.
