"This was a mistake."

Last week, I drove my sister-in-law and my girlfriend to get pedicures. The goal was to leave them there to bond with each other, or whatever it is women do when men aren't around. My brother and I planned to kill time somewhere manly, like a dank bar or a bowling alley, but by the time we arrived, the merits of pedicures had been explained to us thoroughly, and when the lady at the front desk asked, "Four?" I immediately said yes. Why not?
