A day out to the beach

Your eyes fly open at the sound of your alarm singing your favorite song. You sit up groggily and rub your head, "I really shouldn't have gone to that party last night..." You mutter to yourself while turning off the alarm. You rub your face and head to the bathroom to splash some water on your face, after that, you look at the time to see its only 7:12. Your sister isn't up yet, But has to be in about a hour. Do you -

Take a shower before she wakes up

Wake her up early

Sneak into her room to see if she's even awake
