You will never know how you feel about someone till you kiss them.
As a much younger man in the late 1970's, I recollect the full frontal lip kisses of the day, the waxy taste of lipstick from so-called aunts and family friends many times removed.
I remember the many awkward first kisses.
Years later I recall the way I learned the "faire la bise", or french cheek kiss, from an Austrian girl in London.
Now I've come to realize, when it comes to the casual kiss, I may have become a complete unknown.
Which speaks volumes really.
I really have to turn the volume back one day.
