Is my wife's competitive nature ruining our lifes?

For the last twenty years my wife has gone to bed waring a miners helmit and lamp. For five years i laughed at her. Fifteen years later...Last night i needed to use the loo,but when i switched the lamp on nothing happened, so i got out of bed, , tripped over my shoes, smashed my head on the set of draws, suddenly! a stong light shone in my eyes, "who's laughing now" she said.
