I’ll have reading material ... not to mention family and friends. I’m perfectly happy to stare into space and do nothing for minutes at a time, too - until I’m interrupted by, “You have to take me to the bathroom!”
Rest assured; it changes.
First it becomes; You have to take me to the mall!
Then it becomes; You have to take me to my boy(girl)friend's!
Be sure of the space wherein you stare. I have a bad habit of doing that, mentally completely disconnected from anything in field of vision while I think on other things, and it has in the past caused me grief when folks think I am staring at them. (If they move and see that my eyes don't track, they may understand: I'm not looking, I'm not registering.)
