got my aunt kicked out of her house, need apology gift ideas.

I was housesitting for my aunt (I'll call her K) the other night and me and my friends decided to partake in some mild marijuana use in her backyard. What I did not know at the time was that the next door neighbor had a camera pointing directly into K's backyard, and it was all caught on video. The landlord was upset to say the least. K is most likely going to have to find somewhere else to live now. I feel insanely guilty because of this, and I am planning to get her a card and flowers when she returns from her trip. I feel like I need to get her something more substantial, what are good gifts for women in their thirties? she has no kids and is not married.
