Thought I'd add to the previous answer since I was in a hurry earlier
When I leave my house and don't take my dog with me, she response by running through the house and getting into any food she can get her mouth into. She doesn't do it in the same manner as when she is eating normally. She makes sounds unlike the quiet manner she eats otherwise. If I don't take her for walks, she either digs holes in the yard or tears up the stuffed animals. She also makes noises and pulls on my clothes or tugs at my hands when she wants me to take her for a walk.
Depending on the human, there could be different interpretations:
1) the dog is angry
2) the dog is frustrated
3) the dog is getting back at me (or some sort of revenge)
4) the dog's feelings are hurt
5) the dog is stressed
6) the dog is scared
7) the dog is anxious
8) the dog doesn't want to stay home alone
9) the dog wants his walk, etc
Since the dog can't write or speak, a human can only guess what she is feeling. Some humans don't even think animals have feelings and some go as far as thinking they don't feel pain. So researchers can only make conclusions about animals from observation.
I enjoy all opinions and I love to watch animal programs and scientific programs and I love learning and I love watching PBS. .
Nothing wrong with believing in nothing and nothing wrong with believing in everything.
I think there is something wrong if one becomes fanatical or takes everything as 100 percent truth.
I think it is healthy to be open to opinions.
But no one likes to be taken advange of out of greed. No need for anyone to have several cars sitting in their garage just for some sort of status and to have earned the money for those vehicles by excessive lying.
\But then again, lying is one quality that distinguishes humans from animals. Animals can't lie because they can't talk or write. But there maybe other reasons too.
Something's we know are true like a car can be used to drive to work in and a washing machine works for washing clothes in. Those are facts, but I don't spend my energy trying to figure out how it works. I might spend time in awe at human intelligence or human inspiration and how someone was able to put their thoughts to make such fantastic machines.
It is easy to ignore the truth and live ones life. No need to be fanatical about the truth either.
I enjoyed learning psychology,etc in college and taking tests on what I read, but I did not always take everything I read as fact. I have still been able to graduate from college and have a job and relationships, and use the internet, and have a normal lifeetc with this sort of thinking.
