What is affinity?

Affinity is when something really likes being close to another thing, just like your favorite toy loves being near you.

Imagine you have a teddy bear that you carry everywhere. Every time you sit down, you put it on the chair next to you. Every time you go to bed, you tuck it under your blanket. That's affinity, your teddy bear has a strong connection to you, and it always wants to be near you.

Why It Matters

Think of affinity like a friendship between two things. When you have a favorite snack, you always reach for that one first, that’s affinity too! Your brain says, “I know this snack, and I really like it,” so it picks it every time.

Sometimes, affinity helps us make choices without even thinking about it. Like when you pick your favorite shirt to wear in the morning, it just feels right because of the affinity between you and that shirt.
