I've got crush on a few teachers. And crush, not as in, I secretly dream about banging them (for the most part), nor do I keep my fingers crossed every day that they will invite me to the prom. It's more of an exaggerated belief that we have some magical connection between us, one that is communicated in small gestures, signs and symbols. And maybe, one day, an eternal union of our souls in nirvana. For my own health, I hope I'm joking.
Crush in the sense that someone has an incredible amount of significance and impact, unknowingly, for the most part.
I also justify this by saying that I feel that some teachers are in my karass*, that is, the group of people who lead me to my life's meaning.
Kurt Vonnegut is love, by the way.
