Over the weekend I met with a couple who mentioned that their parents had not met yet. They didn't know what to do or how to arrange this. I told them it was a good idea to try to get this done before the wedding!
Traditionally, the grooms parents are supposed to set up this meeting if it happens post engagement. But these days when parents live out of town and schedules are hectic the bride and groom should go about setting up the meeting. I suggest inviting both sets of parents into town for dinner at a neutral location - maybe the couples favorite restaurant or a potential wedding location.
The good thing is there will be lots to talk about - getting to know you things as well as all things wedding!
