Uh.... No BUENO at ALL!!!!

So, let me just say I am a pretty generous person. Not to toot my own little horn, but I am not very selfish and very rarely have I ever put myself before anyone else (maybe that's my problem?). Well, I live in a 2 bedroom apartment, which most girls would convert the extra room into a HUGE walk in closet, but my bedroom already has one because I have way TOO many purses and shoes.... ANYWAY, I have a guest room, that's very inviting and very comfy bed. Which brings me to post this... my foster sister recently moved back into SA from Pipe Creek (about 45 minutes west of SA) so she asked me "Can I stay with you?" I said "Sure, but I'm not home a lot and Wednesday thru Sunday afternoon Mal stays with me or vice versa." She said "that's cool." So, when I came home for lunch yesterday I was in UTTER shock and AWE to see her asleep NOT in the guest room, BUT in MY room in MY bed!!!! If this were my mom or biological sister or even sister in laws I'd still have A HUGE issue with this, you do not come into someone's home and sleep in their bed when there is a perfectly good guest room down the hall!!!! I told Mal this last night and I literally thought I was going to have to pick his jaw up off the floor. So, this morning when we left for work, I made sure to lock the bedroom door, a.) to keep the cats out and b.) to keep the foster sister out. So, she text me when she got home from work "Is everything ok? Your bedroom door is locked" Uh yeah to keep you out..... UGH!!!!
