1. I'm 5'2"
2. I just find it to be a stupid question in the first place. Some people just don't really like kids or want them. Some people might be offended by it if they are trying to hide the fact that they can't have kids by saying they don't want them. Anyone can be offended by anything at any time. I just feel like it is a question that doesn't need to be asked.
3. I think it depends on how people are raised and their age. There seems to be a huge generational gap between what today's kids expect and what we felt entitled to as kids. I think I was a little spoiled and therefore feel more entitled which means I am not as well adjusted as other people my age. :-(
