Mother In Lawless

The old woman with the gun is my mother-in-law.
But she’s more like a mother-in-lawless.
She breaks into banks with ease, breaking out of jail and nursing homes even easier.
We’re not a close family, but we’re kept under a close watch as hostages. Instead of knitting us sweaters, she keeps us tied up and gagged.
And I don’t drive the getaway car because I’m a part of her gang. I drive it because she’s a horrible driver and her license was revoked by the state.
I’m only doing it to save lives.
Now put the money in the sack.
