Every single ISFJ I know is in a perpetual state of tiredness and they are always lying down to rest with their eyes shut. They all love to lie down in bed. Not even to sleep, mind you. Not even to read or talk on the phone or anything. Just to "rest." Doesn't matter if it's a 3 day weekend and they got 12 hours of sleep every night. All the ISFJs I've ever even seen are always doing this. It drives me NUTS! I would be bored out of my damn mind if I did that. I don't think I've ever taken a "rest" in my life. Sleep, yes. Nap, yes. But a rest? What the hell is that? I just want to slap them across the face and yell, "There's a world out there looking to be lived! Now get the hell up and live it!"
So does anybody think this is specific to the ISFJs I know or do you suppose it might be a unique characteristic of the ISFJ type in general?
