When my mother-in-law, Margaret, demanded a monthly allowance from my inheritance, I didn't know whether to laugh or scream. I agreed to her request, though—not in the way she expected. My husband Tom was caught between disbelief and amusement. We’d all had our fair share of conflicts, but this took the cake. My best friend, Sarah, thought it was some kind of joke. With all our history, Margaret should’ve known better than to underestimate me this time. Little did she know, the way I planned to handle her request would turn our family dynamics upside down.
