When I found out I was pregnant with my first child, I started saying the phrase “We’re pregnant.” And when my husband corrected me, and said he wasn’t pregnant, I was hurt. I was mad at him because I felt like he wasn’t joining me in the journey. Then around week six, when I started puking four times a day, and when I started getting coffee withdrawal headaches, and when I became a hormonal roller-coaster, I loved him so much for acknowledging the truth. We were not pregnant. I was pregnant.
Sure, we were having a baby together, we were going to become parents, but I was the one who was pregnant. That’s why I love what Mila Kunis had to say on “Jimmy Kimmel Live” last night:

Because as Mila said you’re not pregnant unless you have to “squeeze a watermelon-sized person out of your lady-hole.”
Semi-related: On the night her learned that he had won the presidential election of 1860, Abraham Lincoln returned home from the telegraph office and said to his wife, “Mary, we’re elected.”
(Meaning: I have a Country to run, and you have my kids to take care of.)
