This is not an imposition, it’s a kindness. The point of a suspense file isn’t to nag others into living up to their commitments, it’s to form a network of support among collaborators where we all help one another make those conscious choices about what we’re not going to do, rather than having the stuff we really value slip away because we forgot about it.
This is important…I’ve often wondered about good boundaries around reminding other people of their obligations. Should I send out a reminder email about the meeting, or assume we’re all adults? Instead of seeing it though through the expectation of perfection, if I admit that we all need help (this is why I have a Getting Things Done system after all), reminding others turns into a collaborative system in which we’re all trying to do our best.
