Bad mothering?

Have you ever had one of those days when you feel like you have been a terrible mother (or father)? And it never fails that those are the days that the children make you really feel like a bad mother. Well, I decided to attempt my first garage sale a week ago with a good friend - and I will never do one again. It was a lot of work, and I saved up so much junk and didn't even get rid of half of it. In the process though, I guess I successfully neglected my children and the dog became the nanny!!
