<human>: Give me the gist of the text in a nutshell

I have been thinking about this a lot lately. Am a mid-20's male with a SO that has a desire for a couple rug rats. Problem is... all my adult life I have been staunchly against the concept. Even though as of late I have had an inkling that I might be ready for them. Have a girl I care about, making money to spare, but not sure if these feeling are more that of wanting to move into a mentor figure rather than a father. Almost feels that any yearning I have for fatherhood could be quenched by a Big Brothers program or something similar. See couples without children in their mid-30's and they travel a few times a year, seem happy, energetic with a splendid marriage. However, those couples with children at the same age seem trapped, time-contrained, drained, and enjoying a merely content marriage. Whilst they may say, "Ya sure *this and that*, but I wouldn't trade it for the world." It seems like a cliche' answer that all parents have to say... Almost as if what one reads through their eyes is, "I haven't slept in days, been laid in months, and didn't know life could be this torturous outside of Abu Ghraib!" I mean, sure I can believe that they feel they wouldn't trade that life for anything, but I can't help but think if it isn't a coping mechanism, or the fairly well know change in brain chemistry either leading up to birth or shortly thereafter that compels them to feel that way... when everyone without kids can see right through it. I'd give odds though that those with kids are just chuckling now saying you can never understand until you have been there.... 

Anyways, I realize that a post at 1am will likely get no love, but was hoping the infinite knowledge of insomniac Redditors could steer me to some unknown objective position with regard to children that I have yet to ponder :)
<bot>: Don't think kids are worth the energy input to happiness output ratio... Hope reddit can either enforce my ideas or lead me to new ones... Thanks
