I think I would be grateful that it was a spoon and not a used needle sticking out of the shorts. And the bloody paper towel would also give me cause for concern.
I don't think I'd handle any of his things again, but then that's me. I would be scared to death of what HIS addiction could do to ME.
Food for thought. Sending my prayers because it's not a nice place that you are at right now.
Hugs
