My best friend and MOH still lives at home with her parents. Her twin brother also still lives at home. Her parents have always been very kind to me and I intend to invite them to my wedding. I'm wondering if it will seem like I'm purposefully excluding her brother if I invite everyone else in the house except him. He is 25 years old so obviously he wouldn't be on his parents invite anyway, but I'm wondering if because is twin sister is my MOH I should extend him a courtesy invite? Thoughts?
