I love my FMIL. She's a great woman. But she's surely set in her ways and there is nothing around that one.
She asked what I'm going to register for as far as place settings. I showed her my Kohl's registry and she said "you need more than 8, change that to 12". Then she asked where else we are going to register and I said Target. She then started listing off all of these local stores and I told her no. I told her we aren't going to register all over the place, because quite frankly, we prefer cash. It's a DW, so the less gifts to trek back, the better.
Next she asked how I was going to word that on the invite and I flat out said "I'm not! There will be no mention of registry or gifts at all on the invite." She wanted to know how people were supposed to know what to give us. So I replied "Well, word of mouth can spread that we're registered at Kohl's and Target, but a reminder can also be made that we are traveling." She didn't like that idea at all and said "well, you need to make sure people know or you aren't getting anything at all." I told her I don't care and that I'm not getting married for the gifts.
Things are done differently here- different than what I'm used to. But I'm sure not going to throw out tact and etiquette just because so many others do!
Just because you saw it on Four Weddings, doesn't mean it's a good idea.
