When I came home a woman was stealing part of the giant plant in the garden. I allowed her to continue because it's not my plant and the woman upstairs is never actually here, and because she said she needed it and I was amused by imagining what she could possibly need it for.

Then I went out again a few minutes later and she was still struggling to break off the bit she needed so I fetched a knife and helped her out, for which she thanked me profusely.

I'm not sure whether helping someone steal something from my garden was a good deed or not.
