I was always warned you'd fall out with your mum over something about your wedding. Turns out (unsurprisingly) for me, it's my dad who's becoming a FotB-zilla...
We are getting married in a church and the pews fit 5 people each. I'm therefore planning on putting 'reserved' spots on the first two pews for the following people:
My parents
My sister and her boyfriend
Further 4 bridesmaids + 1 bridesmaid's boyfriend (others are single)
His mum
His nan
His best man
Further 3 groomsmen + their 3 girlfriends
My friend who is doing a reading plus her boyfriend
That's it. However, my dad is insistent that we put down reserved spots for all family members - aunties, uncles, cousins, cousin's children etc. It's madness. First off, that's an additional 40 people, meaning literally half the church will be reserved. Secondly, without wanting to sound callous I am so much closer to many of my friends who are attending than my family members, and I resent the fact that because of blood some of our closest friends will be stuck at the back while an auntie I've not seen since a funeral 2 years ago is in the third row. Finally - I'm not saying they can't sit up front! It's first come first served - if they really care that much about getting a seat at the front half of the church they are welcome to turn up early and grab one...
Dad is trying to tell me that this is perfectly normal at weddings if you're doing it properly (which is news to me after the 18 or so I've attended since I hit my late 20s...) I've told him that this isn't happening and he's sulking (plus ça change!) - but I did want to check I wasn't making a horrible faux pas 
Did you reserve seating at the church/registry office etc? If so who did you reserve for?
