A small concern ignored repeatedly can become a large part of a relationship.

Nothing grows faster than an issue that gets raised and set aside. The first mention is easy and cheap, and by the tenth it has stopped being about the thing itself and become about not being heard, which is far harder to repair. Size in a relationship is a function of repetition rather than importance. Small and recurring beats large and resolved.

Think of something a person close to you has mentioned more than twice. Deal with the actual item this week, and say that you noticed it had come up before.
