Don't know if etiquette is the right word but its the only one i can think of that will fit.
my MOH is my sister, whose a little bitter that I'm getting married before her as shes two years older. She has no intentions of planning a hen do, which is fair enough. My friends wanted to plan one and have, i have no idea what it will entail, i only know the day it'll be. They said to me the other day "I'll let you know how much your share costs nearer the time"... I'm on a really REALLY restricted budget - as in we're scraping pennys and not eating for the last week of the month at the moment, times are hard. I worry they'll say "oh yeah, your share if £50" and I cant afford that (we had a custody battle that ended in January but were left with an £11K bill to settle, it'll be settled in October but is costing us £800 a month).
I dont want to seem ungrateful or rude but how do i turn round and say "dont make it more than £20"?
