Productive Person: "Why don't you get a job?"
WGS Person: "I can't. All the jobs are either too physical, stressful, or both. I am on disability for my back, knees, ankles, and feet and I had that mental breakdown last year."
Productive Person: "Your physical disabilities are obviously caused by being 150 lbs overweight and you got caught with alcohol and drugs on the job and then claimed they were coping methods to prevent a mental breakdown."
WGS Person: "You all don't know what it was like. Work was so stressful. That is why I am physically and mentally disabled."
Productive Person: "Yes, I forgot, you are the only person who has stress at work. Don't worry though, everyone else will work to take care of you."
