Just a Little Jealousy

Ugh!  I just found out (via Facebook, of course) that another person I know, who I'm not really friends with but we attended the same high school, is pregnant!  I know it shouldn't get me down, but I'll be honest, it kind of pisses me off.  To me this one is even worse than the last one because I really don't think this couple is fit to raise a child, based on their lifestyle.  Their lives seem to revolve around drinking and partying.  Why do they even want a baby?  Don't they realize they can't do that when they have a baby?  It's hard to imagine her not drinking while she's pregnant, too, since she seems to drink all the time.  I know I'm being jealous and judgmental, but I know some of you will understand me!  Why is getting pregnant so easy for everyone but me?
