Last month when I went to Germany someone was asking me "When is it due?" I pretended not to know what the heck they were talking about, even though I pretty soon figured that they were thinking I was pregnant. I'm just somewhat overweight, though. And they didn't notice my braces! I almost told them the date my braces are due to come off. Some people just pay attention to the wrong things :-)
And that was not the only person who asked. My mom told me that someone inquired about the same thing after I had left. I hope they're all embarrassed when they find out what's really going on.
