I offer no justifications and I recognize that in many cases my choices are irrational, but there are a few things I dislike beyond the scope of my ability to explain.
1) Spilt foyer houses (in which the front door opens on to a landing with half-staircases going up and down). I admit this predisposition is shaped by my work, because this is a house in which no matter where find a patient, you're going to have to carry them either up- or downstairs.
2) Municipal buses that are designed to look like trolleys
3) Candles that smell like food
4) Fruit in salads
