I'm still kind of skeptical, but I had moments that increased my belief:
After my dad died, about 1-2 weeks later, I was looking out the window and a hummingbird straight up flew up to it. Like the little dude was a foot away from my face. The little one was just staring at me for a few seconds before another hummingbird chased it away.
Then about a week later when I was sitting outside, another hummingbird flew close to me. It was about 3-4 feet away. It just stayed idle for a few seconds before bouncing.
This past father's day there was a bee on my window screen. Was just chilling there for about an hour. Never had a bee hang out or even fly up to my window.
My father and I weren't close, but I still have love for him.
