Like dogs, humans can experience separation anxiety, although usually for rational reasons. People generally don’t feel anxiety because their spouse went to work or their kid went to school. But it’s normal to feel it if your spouse works as a firefighter, or it’s your kid’s first day at a new school; worse if your kid is a teen who just got their license. The Power Of Love There is one irrational reason humans will have separation anxiety, though. That happens when we fall in love. When the object of our affections isn’t around, nothing feels right in the world.
