This is my life

I'm sorry to hear that work is still being a major pain.

Yay for you doing this, too! I am shamelessly repeating my questions to recessional, because Reasons. (Mainly because I want to see your explanations for them. :D)

Given the group of 1, 3, 7, 9, and 14: who fills each role in their 5 man band? What role does their group serve?

2, 8, 10, 13: when they get together, is it for a book club, stitch'n'bitch, RPG/boardgame group, or potluck gathering? Depending on which is chosen, what's their favorite book genre/craft/game/cuisine?

4 & 6 play a game of "Marry, Shag, Cliff" with 5, 11, and 12 as the options. What are their choices?

Which person on the list is 15's best friend, and who is their worst enemy?
