The vibe..has anyone else experienced this?

This is the weirdest thing, but why is it that when you meet someone you click with really well, it's so exciting? It seems like even normal things become the best. This has happened to me before with different sexes, but this time I really noticed it, and I was kind of weirded out by it. Why the heck does that happen? How are human beings able to sync like that? It's so weird. Share your experiences, comments, or thoughts.
