400 thousand dollars

My handicapped sister is on a mission with my parents in Utah. She emailed me this today:

I wrote back:

Melanie,

Sweet. I could use an extra 400 thousand dollars. When will you be sending it?

Love you,
Amber

She makes me laugh because I have no clue where she gets these things from. And when did she start signing "Mel" as her name. She's too funny.
