Do We Have This One?
? Needs a Better Title
, Needs More Examples
: How much someone likes/dislikes something decreases proportionally to the length of time that person is exposed to that thing.
Most often occuring with a song despised by a person, the song becomes trapped on repeat and after awhile the person becomes to "love" it. The inverse might happen with a song the person likes, it becomes annoying or even maddening to them.
Characters may also build an immunity to people they dislike. Specifically at the start of a series when the main two leads are exact opposites, (One's a straight-laced lawyer with OCD, the other's a wild child, slob who can't hold down a job and they're stuck living together!
). After a few adventures the two main characters may become best friends or at least develop an appreciation with the other.
Another variation is with someone who doesn't like babies. They're terrified of responsibility, of the possibility of somehow hurting one and then they spend a few hours forced to take care of an infant and they learn that it's not so bad. Someone may even tell them that one day they'll make a great parent.
