DH and BM each get one week (7 days) of summer vacation each summer (to be taken during summer break from school). They are required to give 30 days notice of their vacation selection. They alternate who gets "first pick" each year and that communication has to be made by March 1. Vacation supersedes all regular visitation schedules and holidays (specifically says that in the agreement).
BM gets first pick in odd years; she notified DH of her choice back in January.
DH sent an email a few days ago telling her that his week selection was July 3-10 (coincides with his father visiting from out of state).
BM replied and said "no".
LOL .. it literally made me laugh.
