My fiance proposed to me a little over two months ago and we have already started planning, including setting a date and putting our deposit down on the venue. Our families have known our date in comcrete for a few weeks now. Yesterday my sister called me and told me she was engaged and they were thinking of having the wedding within a couple weeks of ours. Since the conversation with her I have been getting more frusterated with the whole situation. Not to mention the fact that I feel like it's rude, but that would also mean a lot of stress for my whole family who are all helping out in their own way toward my wedding, and probably will be with hers. I was thinking of politely asking her to think of moving her date for the sake of everyone involved and lend my hand to working with her to help with her wedding and ideas if she wants. Is that too rude?
