A rule that protects the majority still owes an explanation to the person it predictably harms.

A rule that helps most people can still fall heavily on a few, and knowing in advance who those few are creates an obligation. Being outvoted is not the same as being ignored. At minimum, the person who will bear the cost is owed a real account of why the rule is set this way and what was considered on their behalf.

If you write policy of any kind, even household policy, name the person it will hurt and go and talk to them. Ask whether an exception is possible and, if it is not, say why to their face. The explanation will not remove the cost, and it changes whether they were treated as a person or as rounding.
