Right. It’s a smallish, brunch wedding. Hardly a big extravagant wedding affair that would outshine another wedding. (I think it sounds lovely @veritek). The only people overlapping are three guests.
I mean, when is the acceptable amount of time you should not “upstage” someone and put your life on hold? 3 months? 6 months? A year?
I actually remember that my ex-fiance’s older sister got engaged a few weeks after the ex-fiance and I did. She was going to plan her wedding for a couple of months after ours. I couldn’t have cared less! In the grand scheme of things, is what comes after, the marriage, the most important part?
EDT: When you think about it, they already put their engagement on hold to give his sister some “look at me” time. Now they have to put the wedding on hold? Or get married ASAP? And what’s next? If the future SIL gets pregnant first, do they have to wait a certain amount of time until after her baby is born to get pregnant? If this were a week or two, I’d probably advise differently. 8 weeks is plenty.
