There is a girl at work who was quite slim. Then she got married and a little while later she suddenly stacked on weight and started wearing empire line drapey tops, and I unfortunately made the same mistake. She won't forget it. I have to work with her every day. Unfortunately I am now pretty sure she is pregnant (days off sick, sudden appearance of lots of healthy snacks on her desk, big breasts) but of course I just have to wait and feign great suprise when she makes the announcement.
