I don't much pay attention to the others, other than with Nora and Kinko, and Paul and Leora.
But yes, I very much agree with you that Kinko lives a very boring life, and I am surprised that he and Nora don't go out very much. And your also right, it doesn't just have to be at a club all the time. The idea of a nice picnic somewhere pretty can make for a nice day too.
But seriously, don't you think that a little spontaneity in the sex department would be nice once in a while on the part of Kinko. When I was young, I was always rather smart or daring in that way at times, so naturally it sort of baffles me to watch him be so polarizing and dull all the time.
