Context We See People In
If you have ten shirts and uniformly spread out wearing them, you would repeat a shirt every two weeks (assuming a 5-day working week).
If you have a recurring meeting with someone everyday, they would come across the variation and probably not spend too much attention on one single shirt. At the other end, if you are meeting them once every two weeks at regular intervals, they might think you only have one shirt you always wear.
In most cases, our randomness in shirt selection probably addresses this, but that’s not the point of this post. The point is extending this thought to beyond fashion: one thing to ask yourself when pigeonholing someone is if you always see them in the same context. Maybe you’d encounter a different picture if you occasionally saw them on a Thursday rather than a Monday.
