One of my best friends from college now lives a plane ride away from me and has 2 young kids, but we still stay in touch via email etc. I invited her to my wedding, fully expecting that she may not be able to come because of the kids. So it's not the fact that she can't come--but the way she worded it. First she said she really hoped she could come and that she'd let me know. Then she said she decided to book a last minute vacation for her family, so she can't come to my wedding because she can't take more time off work. (I don't see why my wedding would require her to take any more than 1/2 a day off work, if that). Anyway...obviously I understand that family comes first, but I thought it was pretty rude to basically tell me she can't come because she'd rather go somewhere else. Had she just said "no," I would have been more understanding.
