So my FI is pretty stressed at the moment. I'm doing the majority of wedding planning though he weighs in on every decisions and gets "assignments" from time to time. Two of those tasks were to order the groomsman gifts and order the suits. Both arrived late last week and there were problems with both!
The gifts were grill sets with a monogrammed case, but FI didn't know that the last name initial goes in the middle and of course didn't read the directions (there were three boxes clearly labeled, first name, last name, middle name). Honestly, I laughed at him, and it's okay. Whenever someone asks the GM why their initials are wrong they can tell a funny story about FI.
The suits were custom made via some website in Asia. FI totally screwed up his measurements. I think he can have the jacket and vest tailored a little, but the pants totally have to be reordered. Fortunately we are ahead of schedule so he has time... but he was really pissed at himself and keeps making comments about it. I'll admit, that I am annoyed with this mistake (he didn't measure his waist, just wrote his jean size!) but he's beating himself up enough that I don't need to say anything.
I joke that he does it on purpose so I don't give him more to do. But has your FI messed up anything wedding related?
