I am not a fan of weddings at all, and could easily miss them.
The thing for me is that they are all just so similar. If you have been to 5 or 6 over your lifetime then they call become a bit 'samey'.
You hear the same gags in the speeches, yet everybody laughs at the same jokes they have heard over the years. The same sickly lines about the mother-in-law, handing over flowers etc. Its the same old formula that is the tedious bit for me - no-one ever tries anything different, because all this stuff is expected of them.
For me weddings only get fun at around 11pm onwards, when everybody is well loosened up and the craic gets going, with it turning into any other night out. But you can keep the rest of the day up to that point.
