mom applies computer studies to real life-

[i've been educating mom on the wonders of ctrl+a/c/n/v/s/z/y on word docs]

me: so remember, ctrl+z is to undo, ctrl+y is to redo.

mom pauses for awhile, then-

mom: so if i want nat to go back to that cute, sweet little boy, i press ctrl+z?

me: [startled, but-] yes. and let's say you press ctrl+z too many times and he becomes an amoebae and goes back to your womb, what do you press?

mom: mm. ctrl+y?

clever mommy.
