Let's Play the Stanley Parable 06: Stanley Makes Odd Choices
139While many people expect other people to make right and wrong choices and as well as choices that are good or bad, few people expect someone to make an odd choice. A truly bizarre choice can throw people off which is why you'll typically get a peculiar look and maybe some mutterings behind your back after you've made it and they think you can't hear them. The exception to this is when you always make odd choices to the point that people have come to expect of you. That doesn't make your choices any less odd but the fact that they're waiting for it means that to keep getting that bemused look you need to try extra hard each time, an arms face of peculiarity you will eventually lose.
Note that odd choices are not exclusive of all the other types of choice; they can be good or bad as well as right or wrong in equal measure. They do tend to put the person making them in stranger situations that other people may not end up in however.
