More ways to sway opinions

Feasts are great, and I'd like more of them. But I'd also like there to be other ways to sway opinions. Or maybe even allow opinions to change based on people, kind of like how the opposite happens:

Example:
IF

Toe loves Flick

AND
Toe hears that Flick loves Vembraces
THEN
Toe's opinion of Vembraces increases by a very small amount
