text: the girl from "the nativity story" is prego in real life.  u mean to tell me 15 year olds have sex so young? ok, i just try to picture myself at 15.  i was not thinking of sex.  not even knew what it was.   i'm just trying to picture the star of the movie, just 15, going into her bedroom with her boyfriend, (or maybe they rented a hotel, as i'm sure she lives with her parents still).    so she's going into the bedroom (her parents allowed this?  no one kept a watchful eye?), and then they take their clothes off and do it?    "lets use a condom baby."  "oh no lets not"  "ok, it will be best without a condom."  "did you do your algebra homework that is due tomorrow"  "of course not!, all i was thinking was coming here and doing you"  ok, i just doooon't get it. can anyone figure it out for me? algebra wasn't a high school subject back then... (calculus was introduced in 1600 something by isaac newton) average life span was what? 30-40 years? romeo and juliet were young teens in the 1500's nathan hale (give me liberty, or give me death)= he graduated from harvard university at age 14 of course he didn't have to study the civil war, world war 2...etc  and one more thing... they didn't use condoms in those days, but god could have if he wanted to, but they were ttc
