Why can't we be friends?

We see each other 5 days a week. 8 hours a day. We breathe the same air and laugh at the same types of things, watch some of the same movies, listen to some of the same movies. We even like some of the same foods. But, we can't be friends. Why? I'm not sure. I feel like maybe it's inappropriate. Although, my feelings for him are completely platonic. I'm talking about my boss by the way. I admire him. I love his company. And in the right setting and time I could say that I have love for him as a human being, as an individual. He's way cool. And yet, I haven't yet offered to accompany him to the local pub for some brews with the guys after work. And we haven't invited him over for dinner yet. Why am I making such a big deal about it? Why can't we be friends??
