been thinking about this, sometimes I can get like a "1" vibe or a "6" vibe from certain people just by watching how they carry themselves. not sure how many of those i'm actually right about though.
more than anything though I can usually tell a 3 just by watching them at work, they get so focused on what they're doing and how they do it that they can take something really boring if they wanted to and almost make it interesting to watch, just to see how intent they get.
for example, some obv 3s (off the top of my head):
can anyone else see people and guess their type like this?
