I just did the same thing here. I found my days were getting too long here. I don't mind the mornings as much but evenings... come 4:30 I am DONE as are the kids! I changed my hours to 7:00-5:00 from 5:30. I sent out a notice TELLING them this was the change and I will no longer be able to accomodate after 5pm as its too much disruption to my family and our evening activities. Most understood. One family asked if 1 day a week I will do 5:15 so we will SEE on that one.
