Parents working many times has little to do with manners.
Also, not all parents rush like that. I work 7 blocks (one traffic light) from my house - we leisure most mornings since none of us need to be at school and work until 8:30. They get home at 3:30 - I get off at 4 and home by 4:06 (depending on the traffic light. I know and truly appreciate that CF couples/individuals do not like to be stereotyped. I don't think it's fair to stereo type parents either because you run into some with bad kids... but if you're going to do it - at least it should be accurate that there are exceptions. :-) all said with deep respect for the CF lifestyle.
