Chepe y Chui y Chincha y Chita y Chana

I love nicknames here.  To my (gringa) ear they have even less relation to the original name than is usual in English.  For example: the nickname for José is Chepe (or Chepito); Jesus is Chui (sounds to the gringa like Chewy); Geovany is Chincha; Felicita is Chita, and I was delighted to learn that Susana is Chana.  You'd notice a preference for the "ch" sound - and somehow that makes sense to me, all those "ch" names sound friendly.  Of course there are nicknames like Rosy and Mari, and if some of the popular English-sounding names, like Marvin and Nelson and Wilson have standard nicknames, I haven't heard them yet.   I'm tempted to try Charvin or Chelson, but that's probably wishful thinking.
