My SO has misphonia, and strongly reacts to many sounds I make like smacking while eating or tapping my foot while thinking. She can also react strongly to noises outside the home, like if a car idles loudly outside.

She works in a kindergarten, and so I asked how she tolerates all those kids making noises while eating and such, given how adverse she is towards the sounds I make.

She said it didn't bother her the slightest as she knew the kids couldn't help it, and the reason my smacking annoyed her for example was because she knew it could be avoided if I just were more careful.
