Who's tired of the "so are you done after this" question?

Raquel • 39, mom of 2 boys, EDD 20JAN2015
I can't stand it! This will be our third child together, we're married, and both work. What's the issue? Why do people feel the need to ask this question? I'm 39, baby girl will be born in Jan, and I turn 40 in April. So ya, most likely this is our last, but something in my heart says maybe not! Idk it just bugs me cuz idk the future or God's plan so how do I know exactly? Thanks ladies, rant over...
