WEDDING SCENARIO Janice Is Excited Because Her Boyfriend Just Asked Her to Her

WEDDING SCENARIO
Janice is excited because her boyfriend just asked her to marry him. Though planning the wedding may be a big hassle for most people, Janice had it easy as her sister, a wedding planner, has taken over the task of planning the entire wedding. Janice should have been the one taking all the decisions, but her sister chose to be the sole decision-maker on account of her professional competence. Since Janice's parents are paying for the wedding, she needs to abide by their wishes even though she might like to have a more extravagant reception than they are willing to pay for. She will be getting married in a church, and the priest said she and her fiancé would have to attend pre-marriage counseling sessions over six weeks. They are not really thrilled about doing that, but they know they can't get married in their church if they don't attend the sessions. Her parents are very frugal, and her mother even suggested that she wear her old prom dress instead of buying a new wedding gown. Janice was mortified when her mother suggested this, saying, "But mom, the dress is pink! What would people think if I wore a pink wedding dress? Wedding gowns are supposed to be white!" So they settled on letting her pick her own gown, but her father had the last say on which one he would allow her to purchase. The wedding day came and went without a hitch, and Janice is now a busy homemaker setting up her new household.
