Further into my pregnancy I'm starting to realize how immature my "friends" are. My friends 21st birthday was the 12th and I explained to her I couldn't drive to go hang out with her and her friends because I had to take out my last pair of contact lenses, I said if anyone wants to pick me up I'll be happy to come. She gets pissed at me. I'm honestly glad af I didn't go because as I found out later everyone got drunk (no designated driver) then went to her house and got high. I guess the reason she wanted me to come was so I could play momma for a bunch of adults acting like children. It might have been okay before I was pregnant to make sure everyone got home safe but now it's my responsibility to care for my child not any of them. And people wonder why I don't want to go anywhere anymore.
