I was first married in 1975 ~ gasp.
I didn't know how to cook ~ gasp, gasp.
Whenever I tried to make gravy, it turned out lumpy.
Finally, my mom told me her secret was to use cornstarch.
She then gave me an empty coffee can to keep the cornstarch in.
(I know, don't end a sentence with a preposition, but....)
Fast forward 36 years, three houses later.
I now live in Roanoke, VA.
This is what I see several times a week.
