Since the day I got the scholarship for the leadership program held at a sleepaway camp, my number one mission has been to keep Mom calm.
Mom: "Jane, you must wear a hat everyday so you don't get heatstroke."
Me: "Sure." Definitely not wearing that dorky safari hat with the neck flap even if it's 100 degrees.
Mom: "Apply sunscreen every half hour and don't forget the back of your neck. Everyone misses that spot."
Me: "Okay." I'm working on a beautiful, bronze tan for the first time in my life.
Mom: "Wear flip-flops all the time to prevent splinters or toe fungus."
Me: "Will do." Yes, that I'll do. Toe fungus sounded nasty.
I agreed to everything, because I knew one 'no' and the tightrope under me would fling me to the bottom of boredom and having to stay home all summer. When we finished breakfast on the DAY, my jailers, aka Mom and Dad, loaded up the car with my stuff with faces pinched as if they'd just drank a whole bottle of vinegar. Grandma patted Mom on the back and said how proud she was of her. Proud of her? What about me? I was the one going away for the first time EVER.
As Dad backed my getaway car out of the driveway, my brother and Grandma waved us off, all smiles. I sat in the back next to Mom’s monstrous notebook, which overflowed with her to-do's and not-to-do's lists, and more what-if's than any normal person could think of, all separated by dividers and color-coded.
I put my headphones on to listen to music and shut out the creepy quiet in the car. Dad
I love the humor in this--the incongruence of Grandma reassuring Mom instead of Jane, the revealing description of Mom via her lists, divided and color-coded, and the way Jane is saying "yes" outwardly but "no" inwardly. One thing that might make it feel even more vivid is to add a few details, like the name of of the camp or even more silly details about the notebook, or what kind of music she's listening to, and also try to think of a more unique way to describe her parents' pinched faces. Good intro! I'm not entirely sure what major conflict to expect in this story, but I don't think you need to show that in the first 250 words. I'm off to read your query now, since I missed doing that first.
