I also find it darkly funny (and not in a good way)- to play a little trick on them and observe the reaction. One night, I knew my wife was shooting up in the bathroom, but I was feeling weak and unable to take any sort of stance, so I said, knock knock, I need to come in and pee. And the spoon was out on the shelf with everything in it, ready to go. So after I peed and stuff I just put the spoon into the toilet (wasting probably like one shot of hers) and didn't flush. I got a very mild chuckle from that, on top of the misery. And then I went back to bed, crying.
