During my college days, I had a roommate that was very busy dating instead of studying. It didn't take too many meetings with these guys to see that most would not even notice I was in the room, would not say hello to me, etc.

When she finally met one that at least noticed my presence on the planet, I was amazed. She eventually married him, and 25 yrs later, they are still together.

Humans can be so stupid on purpose about such cues. We are so lucky our pets remind us to listen to our hearts and our gut feelings.
