I think you are a bit confused as to the norm and social understanding of "average" activities such as marriage, birth and family life. We don't celebrate those things because we are astounded that they were accomplished.. We don't throw showers to say "yay, congratulations on the accomplishment of actually getting a guy to marry you". We do these things to celebrate life, love and happiness with the ones that we hold dearest to our hearts.. It's not like passing a test or getting into law school, we celebrate these things because they excite us, they symbolize two people choosing to stand by one another's side 'til death do them part. And as a woman who has been married less than a year, I can honestly say that I'm not so convinced that being a wife and mother can be referred to as "doing nothing" anymore than running a NASA space station can.
Women endure pain, grief, depression, ridicule and total life transformations every day to have children of their own - but in the end, it's all worth it because I cannot imagine anything more rewarding (and emotionally trying) than being a mother. I have 2 amazing step children, but I have yet to have a child of my own.. A little one to have my blue eyes and my husbands big ol' heart.. Maybe one day. I also know that in my younger years, I caused my parents a few gray hairs. I was far from an angel..
I know, shocker right?
My parents sacrificed a lot for my brother and I, so that we could have what they never got the chance to have. They provided for us and loved us, and we rebelled as children and teenagers often do. To this day - even though we are grown, they would do whatever was humanly possible to help us out no matter what we did or needed. Children are needy. They need food, clothes and water but they also need love, support and guidance. Simply birthing a child doesn't automatically make you the Patron Saint of Mothers (St. Anne is who Google told me fit this title, but I'm not Catholic - so don't hold it against me if it's incorrect).
Maybe that is the case with you, dear blogger? Maybe you had a rough childhood with dead beat parents and thus you justify your doubt in the family system by ridiculing the one thing that makes you fearful.. Fearful that you too, will turn out just like those who raised you? This makes my heart break for you. Even the busiest bustling cities filled with all kinds of amazing and interesting people, thousands of restaurants and Broadway plays are still lonely without someone who truly knows you and loves you no matter what your faults are.
