I eventually got over the feeling. My response is an “already on it” in the sense of a playful “i beat you to it”, and I expect an “awesome, thanks” in turn. That way it’s gratitude and support for each other - since that was the intention to begin with - instead of resentment for an unnecessary reminder.

Imo it helps to remind oneself that mental load is a thing and they’re reminding themselves just as much as you. Getting ahead of the reminder consistently will eventually make the reminder obsolete and lighten the mental load.
