This is an animal family hugging. If the human family is hugging, it could be pictures of different animal families hugging. I think the communication works because there is similarities between the animals and humans. People can identify themselves in the animal families and say "look these animals, they are like us".
I took a picture of my BFF Maddy cheesin. She didn't know I had a camera but she is just so photogenic you would never know! This literally just happened. I am savoring the moments that I spend with her because she is the best. Savor.
