Dear Mary: How can I greet friends without clashing specs?

Q. As an old trout, large in height and breadth, I have taken a leaf out of the documentary Advanced Style (which celebrates elderly chic) and purchased a pair of oversize specs with big solid frames, plain in style, not à la Dame Edna. My problem is that every time I greet a friend and get kissed on one or both cheeks, it is either a clash of specs or I bump them uncomfortably on the cheek with the frames. What to do? To whip the specs off before the greeting seems as if I am expecting a slightly more intimate hallo. To angle my head away seems a bit unfriendly. Or do I just carry on clashing?

A. Since the whole currency of social kissing has been devalued by excess, now would be an excellent moment to rise above the mob and embrace an advanced style of greeting.
