If you were trying to discourage your girlfriend from purchasing shoes, this method would probably only discourage your girlfriend from checking in to shoe stores.
The plan was to use Lamson to parse these e-mails, but apparently it depended on a library that - in a minor version upgrade - totally fucked everything that depended on it by arbitrarily renaming several functions. Unless you specifically installed fucktits version 2.2 - not 2.1, and god help you if you installed 2.3 - it wouldn't work.
After three days, and help from a friend, I just tossed it all in the garbage and resigned myself to living under a pile of her shoes.
