I had an Istj neighbor. You could set your clock by his daily routine. He ended up selling me his car (he had kept track of every single oil change and maintenance record from the time he bought it brand new). Anyway, when he came home from work everyday I would usually be outside on my phone (talking to my best friend). He had the most dead pan demeanor asked me when I planned on having the phone permanently implanted in my ear. I remember seeing him come home one day and on that particular day I was in a zany mood, breaking out in song, singing that he was my favorite neighbor in the whole world. And he looked at me with his dead pan dry serious face and replied: Are you drunk?
I started laughing, and I saw a very rare grin spread across his face......should have told him my silly switch flipped
