I read an anthology of teen short stories probably from the 1960s. The two stories I remember are:
1) a shy, plump girl named Becky loved to bake, but she agreed to take a role in the school play because she had a crush on a boy in the play. The role was motherly (or grandmotherly) so Becky felt she could pull it off even though she wasn’t an actress. The boy crush would come over to “rehearse” but really he was there to spend time with Becky and eat the yummy things that Becky baked. He finally admitted that Becky wasn’t a very good actress, but he wanted to date her because he felt so comfortable with her in her cozy kitchen.
2) A slim, athletic girl who always wore pedal pushers had a special word “v’standen” that she and her dad invented to show that they understood each other, no other words necessary. When she got dressed up in a strapless gown to go out on her first date, her dad made a cold remark about how she looked. He wasn’t actually being mean, he was just shocked at how his little tomboy had grown up. When she came down the stairs to greet her date, her father tried to stammer an apology. She told him “v’standen” and everything was good.
Note: This is NOT “Stories to Live By” from American Girl Magazine. I bought the book, but neither story is in it.
