She should know she won't refuse! She'd rather her sleep somewhere more comfortable where she at least knows where she is. Even if that means her own shadow!
Yes, she's caught her doing that. Even if she thinks she hasn't.
...Surely she does know sneaking in is the last thing she should be doing?
Well, at least she hopes so. Trying to convince her otherwise is a futile effort anyway. She'll just hope she's careful enough to not get the attention of their parents.
She knows this, of course.
Whatever candy she wants, she'll buy it for her. She may as well, seeing as this is one of the rare occasions her sister has called upon her!
...Well, she has faith the day will come where she stops eventually.
Besides, she knows she wouldn't steal from her. After all, she'd probably give it to the thief if she just asked.
That's why she's here. If they won't care for the thief that has their blood, she'll do it.
...Even if she won't listen when her older sister pleads for her to stop stealing.
