Couples who have been married only a few years often remark how there were so many people at their wedding, or even bridal party, who they no longer speak to. They have fallen off the face of the Earth since the wedding. Maybe life shifts, attentions divert, people move away. For the most part, included in this group are people with which your bonds may have been superficial. Do not invite certain people to look good. Do not fear you will look less than if this or that person does not attend your wedding too. So what if they were in your fraternity – be the cool discerning outlier and do not invite everyone. There are other innovative people in your alumni association that will accomplish more and be a better contact for life, and they do not care about being invited to your wedding. Similarly, do not invite people that will attend your wedding just because they too have FOMO. Your wedding day is too meaningful for that.
