In our house we have a saying "Every day is Monday." We have this because every day for us is the same as the last. My husband is a truck driver and has no set schedual, so therefor he could work everday. I stay at home with our two boys and most of the time forget what day it is because we stay at home. We live about 20 minutes from the nearest town and to pack up and go kinda needs to be planned.
I hope that one day our "every day is Monday" will be a good thing because we will have the freedom to do what we want and not have to worry about what day it is or if there is going to be work that day or not.
