Attended a buddy's wedding over the weekend. Not a fan of traditional weddings. Very uncomfortable being in a suit and tie--my one and only circa 1995 suit and tie. A colleague once attended a ceremony/reception on a mountain summit where the guests came in hiking attire and gear (the couple were avid hikers). Now, that sounds like an interesting wedding.
I'm definitely going the informal route. 18th hole, Pebble Beach, come in your golf shoes (soft spikes only please), shorts (Bermuda length) and shirts (collared); and bring a wedge (conforming V grooves) for some after the ceremony fun. Although, as Tiger has demonstrated, it might not be such a good idea to have metal sticks around the wife, in case you're caught checking out the attractive bridesmaid.
When I first started attending weddings as a young adult my thoughts were always the same: I can't believe blah and blah are getting married, that's crazy. After 6 weddings in a year it became not so crazy. It became normal. These days, if you're not married or engaged at a wedding you're very much in the minority.
It's not so bad for us guys, we always have golf and strippers, but I think it's tougher on women with their clock and whatnot. So I tell the single ladies to get back with their asshole ex-boyfriends. He might not be perfect but he's probably good enough. Naturally, they think I'm crazy, but then I give them a copy of Marry Him: The Case for Settling for Mr. Good Enough.
Wedding these days are all about the children. Friends my age--my age--with kids! I can barely take care of myself and they're parents! One buddy has two super cute daughters. It gives me hope. Me and him, we're no Brad Pitts, so if he can have a couple of adorable daughters I might stand a chance. My biggest fear with children is that I'll disappoint them. I know the pain of being disappointed by your parents and it scares the shit out of me that I'll disappoint my kids.
