My wife spent three weeks secretly planning my 40th birthday party. She became terrible at hiding her phone, our friends suddenly stopped answering basic questions, and my brother accidentally texted me about "Saturday setup." I knew almost everything.
I still acted shocked when I entered the room. My wife's face lit up because she genuinely believed she had fooled me. People later teased me for being completely clueless. I accepted the humiliation. She spent weeks creating that moment, and I wasn't going to take it away just to prove I'm observant.
