am i the only one left?

Do you ever feel like people don't have anything else to talk about besides their pregnant bellies? Last night I met a friend at another friend's, and I hadn't seen her in a while, and turns out she's pregnant. The entire conversation was about her doctor and being pregnant and when she's due. I had nothing to contribute to the conversation. She got married after I did, yet people aren't considerate, and although they don't mean to be rude, they are, and it's not right. So there I am being blah and just standing there and smiling and nodding and feeling miserable.
