Accidental Theft... or maybe not.

I might have accidentally stolen some plants for my perennial gardens yesterday. So I'm conflicted... Do you bring attention to the accidental theft or assume that you're good and nothing wrong happened? A lady in my neighborhood cleaned out and thinned a bunch of her gardens, taking out quite a bit of mainly grasses. She then put them in some 5 gallon buckets out by the curb... making it look like they were free for the taking. Me, thinking that free was a pretty sweet deal, loaded them up in my truck and brought them home. It wasn't until this afternoon that I noticed the very tiny sticker on some of the buckets that looked like a label with what the plant was and what could have been a price. Hmmm... who in their right mind, wanting money for their stuff, would have put it out by the curb without a BIG sign stating "FOR SALE"? So, I'm still not sure if she was expecting payment for them... and if so, was she charging extra for the baby slugs that were also in the buckets?
