Love in the fourth dimension

I would like to say that there is another form of love somewhere out there. It's when you realize that you miss the things you love, which would be things such as, for example, astronomy. For me, it would be almost anything. One of those things that I love would be smell. I like taking a smell and experimenting with it in a public place. I see strangers. It's strange. Because they have emotions in their mind. And there needs to be a smell to "Break the ice" per say. Sometimes I see people that think about love as in "I like someone". And here's a problem. After all, you know, they might not realize however that there is love in the fourth dimension. You just need to become more attuned. And yet I have to question why it is that some people like writing, while others like astronomy. How is it that one person is born with an interest, while another has a differing interest? Again, I must admit, this another one of the "The most mysterious phenomena I've ever observed (can you explain?)". Wouldn't you agree?
