FI has been great on the etiquette front.I tell him about all the stuff I learn here, and there is a lot we both take away. For example, we always get invitations that say "Adults Only", and so when FMIL tried to get advise us to put that on the invitations, he said no. Of course she pulled the "Everyone does it!" Line and he said "Just because everyone does it, it doesn't make it right." Yay!!!
Until he made a huge blunder. His bachelor party is this month, and one of his GM told him he would not be able to make it. I could tell FI was a bit bummed, but no biggie. Last night he told me that their softball coach (they play in a league) texted him to tell him that he and the GM booked their tickets for the party. (This is actually cute. Apparently, they are showing up a day later. GM didn't want FI to know, and he just wanted to show up and surprise him. Tender!

) I commented "Oh, you invited coach? Cool." Then a few hours later, it hit me.Coach was not on our wedding list and we didn't send him an invitation! Then it hit me again, one of the other guys going to the bachelor party was ALSO not invited to the wedding. He is one of Best Man's friends, and although we know him and have hung out with him, we're not close with him, so he was never on the list to begin with. FI didn't invite him to the party though, BM did. Still.
So yes, FI has 2 guys going to his bachelor party that he did not invite to the wedding, and invitations went out last week. I told FI he needs to get me those 2 names with their SO's ASAP. Apparently he didn't think it was a big deal to invite these guys to the party and not the wedding. D'oh! But hey, that's the biggest blunder we've made (so far). Not bad, right??
