Which quickly turned into this in my next book, Four Season Friends:
After everyone was tucked in with kisses and books, Sissy called Noreen. She groaned as she exclaimed, “I am turning into my MOTHER!” She explained, “When I was growing up my mother made a lot of phone calls for school. Whenever a vote came to the public that would help St. Mary’s in some way she, and her loyal group of friends, would begin a calling campaign. Of course this was way before the Internet, so phone calls and mailing campaigns were the only way to go. When Mom was on the phone all night long, there would be sometimes when I just had to ask something. Invariably, I would get the snapping fingers with the disapproving look for interrupting her. Today, I snapped my fingers at Julie. I tried to stop myself, but alas they snapped!" Noreen burst out laughing. Years ago I found myself clicking my tongue at something Amanda did and I slapped my own face! The two women laughed until they had tears streaming down their faces and their husbands asking what was so funny!
Inspriation. It comes from all over the place!
