We're not hardwired to mean it every time we say I'm sorry.
We save most of our sympathy for ourselves and give the leftovers to those who have earned it.
We're hardwired to say Fine. Or some variation of it, every time someone asks How are you?
We all know the apologies aren't sincere enough. We're well aware that if we truly cared about someone's well being they would tell us that they're Scared. Because they don't know how they're going to pay the rent. Because their mother has cancer. Because I made myself vulnerable.
