I'm a dirty, dirty liar.I should be above this nonsense. I'm a chemical engineer for God's sake, way too smart to behave this way. But my mom's incessant need to marry me off has finally pushed me over the edge.I'm not sure what the sexy baseball player's excuse is.Now we're pretending to be a happy couple for Christmas, even though we're perfect strangers. How did I get myself into this mess? How will we keep up this charade?Why the hell hadn't I considered the sleeping arrangements?
