Problems with your wife? Time to upgrade the stereo system ...
Wow. That is HILARIOUS. Memories.
My first real girlfriend could (and did) do that under table zipper thing while sitting at my parents dining table - once when we were hosting one of our (well known) senators (congressman? can't remember which now)!
All I can remember is that I damned near choked on my meal, and everyone (incl said senator) looked at me as if to say '
WTF is the matter with that kid?'
Oddly enough, she later became a recording engineer and teacher at a well respected school. Later (recently) I even tracked down some CDs she'd mastered.
Also one of the early Venice Beach residents, she lived there for several years in the early 70s before returning to the east coast.
Long since passed way, sadly.
RIP Robin!!
