I sort of had a teacher crush back in the day with, funnily enough, my english teacher. She was quite hot anyway but she was one of those teachers that just talks to you on a level and never got uptight like most teachers.
I realised I have a talent crush on one of the lead actors in the amdram Rent I'm in. She's insanely stunning to begin with, but she performs with such passion and has such a strong voice that I just want to jump her every time she sings.
