Mary was a really nice person until the money supply dried up, then without her husbands knowledge she took out loans and maxed out credit cards. Once this all came to light she fled and left her husband to bring up the children.
Determined not to let this interfere with her lifestyle, she then embarked on a spending spree to end all spending sprees, and once there was no more credit available, she decided to divorce her husband and take him to the financial cleaners for yet a further supply.
And so that brings us up to date.
I suspect Mary is currently a nice person again, but beware.
