Everybody’s got something that they simply can not put up with.
Some people can’t ride elevators. A friend of mine will visit anyone in the hospital and traverse numerous stairwells to visit the bedridden, as long as they’re on a single digit floor. If you’re on your death-bed in a hospital above the ninth floor, you’d better make sure you’re all prayed up and have dispensed your last goodbye to that particular angel of mercy because she’s not taking an elevator or climbing up ten flights of stairs to wish you auf wieder-bye-bye.
