Ah, trying the old guilt trip, eh? Sorry. I can't buy the notion that Chongo has a sister named Chinga, specially one with the characteristics you ascribe to her. It just doesn't work.

For me to give you comparable treatment, Amos, you must come up with comparable fantasies entirely of your own creation, not merely attach yourself to one of mine and screw around with it by adding a fifth wheel.

Here are a few suggestions:

Invent a transvestite East European neighbour who is driving you crazy with his/her constant knocking on your door to borrow "a cup of sugar", "a rake", "some butter", etc.

Invent a mermaid who communes with you when you go kayaking.

Invent a space alien who visits you on the weekends.

Invent an intelligent cockroach who is organizing a sports league among nightcrawlers.

Whatever....I promise you that I will not create a sister for any of them whose name is a Spanish curse word nor will I otherwise tamper with their essential identity which will be your concern, not mine.
