I Ate My Roommate's Snacks

I snuck into my roommate Sarah's cupboard last night when she was out. I couldn't resist the bag of chips that were calling my name from inside. I thought maybe she wouldn't notice, but this morning she confronted me about it and all I could do was blush. Now every time we're together in our room, I feel so guilty for eating her food without asking. It's like I can see the disappointment on her face every time I look at her.
