I'm having a Mother's Day Brunch here at my home. I've invited the usual members of our families, but have asked that no one bring anything, I will have all of the goodies here.My SIL wrote back that she's bringing something, that THAT'S how she was raised and is not showing up empty handed. I wrote back to please not bring anything it will make the others feel bad-as I have asked people not to bring anything. She wrote back--get this--she's still bringing something; she'll sneak it in! What the heck do I do??? I'd like to not start a fight but how do I put her in her place and still be friendly?
