What does this body language say?
A person was speaking to me, sitting in a chair with their upper body slightly leaning back. They were leaning to the left (toward the window), their head was facing forward (also slightly bent forward), and their gaze was also directed toward me. Their legs were close together, turned to the right (toward the door). Their hands were formed into a triangle at knee height (on the left side), and the triangle was pointed downward.
Did this indicate disinterest? Was this person seeking relaxation in their posture? Or what did this show me?
after the description a completely relaxed attitude, I just looked after and felt quite naturally and relaxed.
Forming the shape of a triangle with the hands improves speaking. You can express yourself more clearly. If someone has difficulties with it, then perhaps because he has problems with it or because it is under tension. Of course, such an attitude can also become habit and thus lose importance.
Otherwise, in particular, attitudes are over-interpreted by women and often mean much less than some see in there.
Either I get the description wrong or the person has been very strange.
No, it’s not disinterest. Bzw is possible, but can show just as relaxed listening.
Maybe in a second. Imagine sitting comfortably in an armchair and your upper body is stretched to the back and at the same time to the left, as if you were lying on the couch in the evening, just showing your legs in the other direction, so to the right and touching their feet on the floor. When we lean the upper body back, our head slips backwards, but it was a bit bent forward. She took her thumb and index finger from both hands and held it together to a triangle on the left side where otherwise the left leg would be sitting. The triangle she formed with her hands showed with the tip, so with her two index fingers down.
Sounds just chilled.
