I've been starting to use a different nickname for Cisco when I go out to catch him - but I had to amend it from my first version.
Everybody has their little names they give to their horses that they use when they are by themselves. Farly was Farles, Phantom is Princess or P-Diddy.
The name I found rolling off my lips when I went out to get Cisco one day recently was C-Man.
It took me a couple of days before I realized that if someone overheard me using that name they would probably hear it slightly differently.
