Here are some photos of another “greeting”: there is always a lot of affection. But also I’m noticing little irritations with each other, as can be seen by their expressions: eyes, ears, snouts, even noses and posture. I can’t read everything that is going on, but a lot is happening. Try looking at the facial expressions and body language. I see constant interaction and communication about feelings, desires, expectations, relationships. For instance, in slide #9 coyote on the left draws his lips up as his sibling approaches; #10 this same coyote gets BETWEEN that sibling and his mother, #11 mother stiffens in reaction.
