Clueless Cashier

I was at the BX with my 2 boys and one of Nolan's friends paying for my things. The cashier asked me if they were all mine. I told only two were but I was actually pregnant with my fourth. Here is the rest of the conversation. Her: "What are you having?" Me: "A girl." Her: " You finally get your girl! That's exciting!" Me: "I already have a girl. I have 2 boys and a girl already." Her: "Oh, well, I was trying to find something positive about having another baby." Me: "This one was well planned and very much wanted."
I just took my bags and left. I think it's sad she probably won't ever feel the love of 4 children. I wouldn't trade it for the world!
