Does that "deep meaning" come to you when you look back, or you felt it when it happened? I have to say I didn't find much meaning in all that grinding, guess that's because I'm never good with human-beings, so I'm frustrated by little tornadoes. My son is almost 6 now so there is some meaning to be found when we do things altogether, but frankly we share very few hobbies and such so it's mostly like throwing darts and see which one sticks.
But all in all, I guess I'm just the kind of person who are not good with persons and who are totally fine to be left alone. I don't even know why I get married -- guess it's just something that everyone does so I did it anyway. Hell, I've been confused by myself since high school and have never truly gotten out of that confusion.
