Yesterday after ivy finished reading me the entirety of "I Can Read With My Eyes Shut!" and then made her own fancy paper chain to count down the days remaining to her fourth birthday, I told kathleen "if she doesn't need me to read or you to do crafts, we are officially irrelevant."
As they left for the store I gave ivy a hug and said "Good-bye, Ready McReaderson!" (That's pronounced "Reedy" McReaderson.)
Having heard that construct before, she replied "Also, Chainy McChainerson and Crafty McCrafterson."
The best is that she always says such things with a straight face, as if that's how everyone talks. (Around here, of course, it is.)
