huh? all the best urban

My sentiments exactly! I guess some elaboration is needed here on both parts.

Oh, I see. Thought it was self-explanatory myself. There are those who's perception of the world is slimey, they see everything in shades of grey; nothing is concrete, nothing really is real, nothing is true. Those of colour vision, acknowledge there are both statements of fact and statements of opinion and feeling. all the best urban
