Well I know I'm not but honestly some people. I'm 8 months pregnant and have rather a large bump I may be having a baby whale. Most people have been very good about saying oh no you're not that big, you can't even see from the back etc.
Went to work today and a colleague I haven't seen for a few weeks saw me and shrieked how huge I was and how I'd put on so much weight - gee thanks! Usually things like this don't bother me at all (with DD1 I was tiny and had people commenting how little I was), but why would you say that, it's just rude!
