Play video games as an adult? Actual console games, Kristy. I bet the Big House had lots of consoles over the years, and she would keep it up as a hobby. Cell phone/tablet games, Mallory would get addicted to some Candy Crush Saga type game.
Plan their family reunion? Jessi and Becca. They are one family that I can see dispersing a bit, so the girls would enjoy arranging something.
Get divorced themselves? I'm not sure. Any of them could be perfectly happy and have a spouse blindside them.
Bail someone out of jail? (Bonus: Who got arrested?) Buy only name brand items when shopping? Start going gray first?
Mary Anne and Kristy was arrested stacey kristy
Have a YouTube channel? use a lot of emojis when texting? learn how to bake bread?
Possibly Dawn between archeaology projects or Mallory between writing novels and possibly several of them during university breaks
Work a fast food job in college?
Probably Kristy, Claudia and Abby at time throughout their university years during the summers
Learn how to code?
All of the BSC ladies...forgive the long rather wordy answer here, but I can see all of them learning to code as early as their high school years and creating websites on the BSC club, then later on the various causes they become active in during their university years and later on as adults.
I can see all of them creating websites championing the covid vaccines.
I can totally see Kristy creating and coding a website advertising for her business and the teams she's coaching.
I can also see her having business and office workplace hacks and tips on her business website also.
Claudia with her art and her advertising firm as well as tips for beginning artists.
Mary Anne would create websites for her counseling services and advocating mental health and also for her humanitarian projects.
She may even help out with Amnesty International to help immigrant families who've been detained or separated.
Stacey maybe for various engineering projects and probably websites combating the massive ignorance about medical science and advocating for vaccines against all illnesses.
She may even help out with the World Health Organization.
Dawn would definitely create websites for the environment and for preserving wildlife and combatting climate change.
Abby for various feminist and civil rights causes.
Jessi maybe for dance and music appreciation and for other causes.
Mallory I can see her creating websites for her books, stories and for writing tips as well as various feminist causes.
I can actually see all of them maybe coding and creating a website magazine sort of akin to Oprah's website giving various life tips and hacks, including parenting, families, mental health, science, friendship, recipies, international affairs, humanitarianism, feminism, combatting bigotry and the teen years as well as a section for the current generation of the BSC back in Stoneybrook to contribute tips.
The BSC are a very proactive group who does not just sit back and passively wait for others to improve life and I cannot see any of them being dependent on a boy or a man to "give" them resources, including doing coding for them.
I also see them all especially growing lots during high school and not being exactly the same as they were in middle school.
Have periodic barbecues at night in their backyard?
Own an RV and take their family on periodic trips with it?
Help a former BSC charge win a full university scholarship by writing a recommendation for their university application?
