Scene: driving to station for the 7:36
Characters : K and me

K: Could you pick up some plumbers putty today?
M: Do you know what my day is like today??!!
K: What? You're only going to one dentist. And then the post office for the passports.
M: And to your aunt's house for christmas!! (exasperation creeping into my voice)
How can you not remember that? Because you aren't going?!
K: Unnecessary information, takes up too much ram.
God knows I don't have enough ram.
