Is it normal to be in love with a 10 year old girl?

I'm 27 and my parents recently persuaded me to attend a Bible study group at someone's house. There were a couple of families there, but most of the people there were older adults. There was one family there with their two daughters. At first I thought the older daughter was cute, she was 13 and wore glasses, but she was very shy. After the study was over, the older adults stayed downstairs to keep talking while the kids went upstairs. I didn't feel comfortable with the rest of the adults so I followed the kids.

I immediately felt this magical attraction and connection to that family's younger daughter. She was 10 and cute, bubbly, and energetic as a button. She was wearing a sweet black top and black leggings. She was really smart and had a very fun personality. She played Twinkle Twinkle Little Star on the piano and told me it was the only song she knew how to play on the piano. We played "monkey in the middle" with a ball and another kid, and me and the girl took turns being the monkey. There was a secret old chest in a closet and she wanted to open it but couldn't reach so I helped her bring it down. There were a lot of old letters inside so I told her we should probably put it back.

I could see how over the course of the night she became more and more comfortable around me and started telling me stories of her friends and family and school and every joke I was saying was making her laugh so hard. She was also making me smile so much, everything she did was so cute and lovable. She was in 5th grade and she told me she was scared about middle school, I told her there was nothing to worry about. She sat down next to me on a couch in the upstairs master bedroom and I almost felt the urge to put my arm around her. Of course we pretended to fight over who got the big pillow, I could tell she wanted it but I just teased her and kept it to myself, but she knew I was just kidding and I gave it to her the second she looked at me with puppy dog eyes and a sweet little pout of her lips. I also asked her if this was the best Thanksgiving ever and she threw her arms in the air and gave me a look of shock and yelled "no, there's no turkey!!" ..that seriously made me laugh so hard. She was so nice and friendly and made me feel so good about myself.

She had this genuine smile that came from the heart and I just fell in love with her. She was so true to herself and comfortable in her own skin. There was no awkwardness about her. It just hurt me that I was 17 years older than her and could never realistically date her, at least not until she was much older and then I'd be in my 40s. I had my eyes on her the whole time, she was the most beautiful thing I ever saw in my life.
