It could have been sarcasm, but I doubt it. Sarcasm is the use of irony to mock or convey contempt, and is a witty form of humor. I sensed no humor in what floodcity wrote.
And as we all know, one of the first symptoms of TDS is completely losing your sense of humor.
Besides, isn't up to floodcity to make the call about whether or not their post was sarcasm?
