The bridal brunch gives the bride an opportunity to spend quality time with members of her family who have come from far and wide to be with her on this special day. It is not a time for her to visit with, or entertain aunt Mary down the street, or cousin Debbie across town. However, if the bride chooses to invite close members of the local family, it is not improper.
Needless to say, the bride who is so thoughtful to take this time out of her wedding day, to make others feel welcome and appreciated, will be remembered forever for her kindness.
Mothers, around the world, are well known for sharing the tears, joys, and triumphs of their children's lives, with both family and friends. It is likely that all the correspondence has been left to mom in the preceding years. The bridal brunch provides an opportunity to renew family bonds, become reacquainted, and begin building bridges to the future.
Another excellent reason for hosting a bridal brunch is many of these guests will arrive the day before the wedding, and the bride may not have another opportunity, for years, to visit with them, as they will likely have returned home before she and the groom come back from their honeymoon.
