In the planning stage of the wedding my good friend that got married a hair over 2 years ago said something along the lines of, “The only thing I regret was not inviting more people.”
We had about 185 people that were attending out of the, I think, 220 or so we invited. Two days later I’m already thinking of people that we should have invited, like the guys that actually set the whole thing up. I worked with them for years, but totally forgot to invite them. Stupid mistake. Spend a lot of time on the invite list. You’ll hardly regret inviting somebody. If they don’t think they should attend they won’t. The only folks that might be offended at an invite is an ex of your spouse.
