Small lies stack like unpaid fees. Eventually the bill shows up all at once.

No single small lie feels like it costs anything, which is precisely how they pile up. Each one also needs maintenance: remembering the version you told, avoiding the person who could check it, adding another to protect the last. The weight is never in one of them, it is in the total, and the total tends to arrive all at once at the worst possible time. By then the lying matters more than whatever you were covering.

Pick the smallest one and correct it this week, quietly, with no scene. Then try a stretch of accurate answers to boring questions. It is a surprising amount of freedom.
