I don't intentionally ship anyone. It's too much work to force an incompatible pairing on Sims that walk away from encounters. I prefer the unexpected variety, although I don't use story progression mods. I never expected that one of my Sims would form such a strong friendship so quickly with his daughter's nanny...but it happened. No romance yet. I didn't expect one of my others...a townie generated to fill an empty lot...to have quite such a whirlwind courtship with one of the Police Detectives, but he did. Still another townie, originally a Mixologist at the Shrieking Llama and moved in, has made Mila Munch his girlfriend with astonishing speed. I find it easier to reshape what's given than to come up with something entirely original.
