Love is a very strange concept for me. I simply can't grasp it.
I understand it to a small degree, but then the rest of it simply escapes my greater knowledge. Like when my parents say that they love each other, but that they're getting a divorce and will probably never see each other again.
Maybe I simply can't grasp the concept because I've never experienced an emotion similar to love or lust or something. Or because no one has loved me (outside of familial relationships, I mean). After all you can't truly understand an emotion until you experience it in one capacity or another.
The closest thing I have to love is me loving food. I really don't think that counts
