You've been thinking that you might have a secret admirer, and you're absolutely right. Your mystery suitor could let those feelings slip today in a very minor way, so minor, in fact, that if you weren't as sharp as you are, and if you didn't pay attention as well as you do, you might not notice it. As it is, you'll need to decide whether to ignore the slip or have some fun, which, of course, depends on your relationship situation.
