Hangin' with the Girls

i was wondering about a couple things. at my school the sisters are required to have lunch together every day, but i have no idea how that works. do you each have to buy something to eat and bring it to the house, or do you all cook something? i know that sometimes they have dinner at the house too, but i don't know how that works either. i would love to know how that works in your sorority b/c i think it might be a little hard to work out if you have a class during the lunch hours. thanks a bunch
