[alt text: an illustration by Will Santino, which depicts two rats sitting on a hill overlooking a glass office building, which is labeled: "Lab Corp". One of the rats is saying to the other, "Of course I'm glad we escaped, I just wish I could say goodbye to cocaine button one more time."]
In Rat Park the rats who were alone and had a choice between the regular water and the drug water always chose the drug water but the rats living in healthy communities preferred the regular water so they could be sober around their loved ones. Although it's just a joke, the cartoon rat feeling the need to say goodbye to the cocaine button it bonded to hit me pretty good today.
