time. I could know I was late, be thinking I should go, and not stop doing something totally insignificant.
When I became a SAHD, I really made an effort for my kids to be on time because I didn't want people to feel sorry for them because of their dad's issues. My older one is 15 and I can count on one hand how many times he has been late to something. But it took a lot of structure and behavioral changes to make it happen.
