Old, But Staying Current On Slang

I'm going to add one more little GG Iva Christmas anecdote while I'm thinking of it. Tis the season after all.

We used to get together on Christmas Eve when my Great Grandma was alive with her son (my mom's dad), his wife, my mom's brother and his wife, and then our family. One evening, after we had finished eating we were kind of all sitting around the table talking. Often times my grandma would kind of dose off at the table when she finished eating. Snoring sometimes....always waking and saying, "Oh. I must've dosed off." She was probably around 90 at the time I'm thinking of. She of course had all her faculties about her, but being that she was born in 1898 and so old, I kind of always thought of her as innocent and vulnerable. So she's kind of dosing here and there and then the conversation turned to someone she knew and she was listening, sitting there all innocent with her white curls and cat-eye shaped glasses. We'll say the woman's name was Gladys. So everyone is talking about Gladys and grandma pipes up and announces assuredly and much offended, "That woman is a klepto!" How on earth my innocent, white-haired grandma knew this Gladys was a klepto or why she chose to use the slang "klepto", rather than kleptomaniac, I'll never know. I can tell you that we all turned and looked at her, and no one really knew what to say, I think we were all trying not to laugh out loud. Oh Great Grandma Iva, so in love with Lawrence Welk, so gifted at making homemade raspberry jam, so easily tickled pink.....so offended by those kleptos.
