Another typical day where you got tired out and drained from all the lesson in school, walking home to sleep already

When you finally reach your home, opening the door... Someone is sitting on the couch, she's a beautiful lady who's the same age as you, the dress she's wearing are fluffy and comfy like she's gonna go to bed.

You then close the door and slowly walk up to them, your mom and dad are at work making you curios on who's this women...

Should you say hi? Or be forward?
