Hi Mies, Gab is informal  and doesn't translate well.  It means idle or trivial talk.  Gift of the gab means you talk effortlessly and usually quite a lot.  I speak nothing but English, and a very, very, very small amount of Spanish.  It's your English, which is  very good, that allows us to communicate.  :-)

Speaking of names, my two given names mean bitter, bringer of light. So if I bring you some light don't expect a cheerful face.  Spell check asked me one time, if I meant Lucifer rather than Lucinda.  I thought that rather insulting.
