Did you know that if you see someone thinking while looking up in the air [looking up], their thinking by remembering images (using their photographic memory.)
This is why you see kids looking up when you ask them to remember back on something [more common with children because they prefer images over text.]
If someone is looking down at their bottom left, the person is probably talking to themselves in their mind, so if you're chatting to them - their probably not listening to what you're saying.
This is important to realise in debates because you see that the person isn't really listening to the points you're making, but instead thinking [in their mind] of ways to refute what you just said.
Whenever you go sleep, you'll realise that your eyes (while closed) are always positioned to the bottom right. Try keeping your eyes closed and keeping them to the bottom left and you'll realise that you can't fall asleep comfortably unless you move them back to the bottom right again.
And Allaah Almighty knows best.
