Your wedding day. It's probably one of the most special, incredible, magical days in a person's life. Well, let me rephrase that last part to "... in a woman's life."
Yes, there are always exceptions, but women for the most part, seem way more into the wedding thing and even the idea of getting married, than men do. That's not a slight, just an observation.
When a woman tells her girlfriends she's getting married, it's usually followed by high-pitched squeals, lots of jumping up and down, and 20 or 30 minutes of hugging.
When a guy tells his buds he's getting married, more often than not, the first thing they ask him is, "Is she pregnant?" That's quickly followed up with a "Then why are you getting married?"
