the tamale lady

One time, months ago, Rachel was home and the tamale lady stopped by to sell some tamales.  Rachel bought some.  We ate them over time.  They were okay.  Without fail, the tamale lady stops by once a month.  On occasion, I've been home and just "didn't have the right change."  She'd even barter with me and sell them pretty cheap.  Now, every time Rachel and I hear an unplanned visitor ring our doorbell, our first thought is "it's the tamale lady, don't open the door."  We try to sneak and look through my bedroom window.  Some days it's her, and others it's someone else.  We still don't answer the door.  If you come a ringing without a calling, you most likely won't get in!
