I do. Its on my manager, though he is more like a colleague and we are the same age/ life stage.
I've tried to pretend I don't, but I just do. I love the way he walks, the sound of his voice, he's interesting and funny and genuinely a good, caring guy. I would never in a million years do anything, even if we were both single, as that would get all weird and awkward and I genuinely love my job and team and don't want to fuck it up.
But God, I just really, really fancy him!
