I Need An Explanation

I need someone to explain something to me.

Between blogs and tv shows 

(Pregnant in Heels, Bringing Home Baby, Teen Mom, Baby Story)

I keep hearing pregnant couples say they don't want the baby 

to "change our social life or lifestyle".

Why on earth are you having a baby?

A child is going to drastically change your life. 

Especially your social life.

If you don't want to give up going out every night and partying,

or getting together with friends 5 nights a week,

why did you get pregnant?

I have a few "friends" on facebook,

and weekend after weekend new pictures are posted of them.

I would swear these people are 18 years old, 

out partying all the weekend long.

You would never guess they have kids at home. 

I don't think parents need to abandon their life, but things are going to change!

Maybe I'm missing something. 

I just can't imagine having a child and honestly thinking life is going to stay the same.
