my mom almost let things slip with my daughter

Well, my mom almost let things slip out with my daughter. She bought me a Dorothy outfit, and came back just as I was feeding my daughter. She then pulled it out and asked me to try it on while my daughter wondered why she had bought me a skirt. Fortunately, my daughter has very short attention span, so probably not much chance she will be telling her mom. Maybe its time I came clean, but I would rather be working in case she makes me fight to see my girl.
