Girlfriend's Weight Gain Denial

Your girlfriend vallery comes into the room mad about how you have been doing the laundry. all of her clothes have been shrinking and you've just caused her last pair of shorts to not fit. she questions you on what settings you are using and insists you must be using hot water and high heat settings. when you tell her you haven't and that perhaps she is the one that is growing, she can't believe you would even suggest it. there's no way she has gained weight, especially enough to outgrow all of her clothes. after arguing with you a bit, she then decides to grab a tape measure to prove if she has really gained our not. once she starts to take her measurements, she's in shock. it wasn't too long ago when she did her measurements last, and the numbers are now way bigger!
