So my friend wants me to babysit her 3 kids 3 times a week from about 7:30PM to 4:00am. I have 3 kids myself and expecting my 4th in just 3 months. Idk how to word it to her that I don't want to do it. I don't really want to give her a bunch of excuses but that's really all I got. To be very honest it's just not a burden I want to take on. How do I say it without coming off wrong?
