Yes, I hide in my room with the door closed and locked to keep the kids out. They still yell through the door. haha
One time, I took the teenager and his friends to a movie. While they watched the movie, I went 2 doors down to Starbucks and studied there for the length of the movie. When I got too cold (the AC was really cranked up), I studied in the car. The younger kids stayed home with Dad. It worked out surprisingly well.
I'll be switching jobs soon and able to work off hours so I hope to study during the day while the kids are in school.
