At the risk of embarrassing myself before the Thireenth, I gotta say that, based on everything I have heard, Keanu is a good guy. I don't think he is gay. He is just unassuming and a bit shy. Run into him on the street and he'll probably ask you to have lunch with him, or so says my sister-in-law when she met him in New Orleans.
I don't think she was lying, but she was likely drunk and high on shrooms, so who knows?
