Just for myself, you will NEVER catch me out of the house in pajamas.
In my opinion, you should just write on your fore head "I Give Up".
I may not take great effort in my looks all the time, but if I have to make a quick trip to the store I will take the time to throw on some jeans and throw my hair up into a ball cap. It's not about caring what other think but having some self respect, in my opinion.
I will also not leave the house sick. I think that should be a common courtesy.
I do not spread my disease if I am aware that I may be contagious.
The closest I ever came to the two is when I had a bad flu, ran out of chicken broth(the only thing I could hold down) called the store, store owner left the cans of broth on the porch for me to collect(in my truck, hopped out in a sweatshirt and yoga pants) and I come paid my bill when I was well as not to spread my sickness with touching door handles, money or merchandise.
Going back to GH's doctor, I would rather have a doctor show up with cowsh*t on his boots than in his PJ's. To me that shows he has a work ethic and was busy rather than being too bothered to throw on a pair of Levis and a clean shirt to show up to work after laying on the couch watching TV all day. If the doctor is taking the time to take care of his cattle, he will most likely take good care of you ;)
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
