I go out all the time at night to movies, dinner, going to see friends. I have friends that work in grocery stores, malls, and they leave at midnight, one or two o'clock if they stock. That's life in the grown up world. You have to be able to function at any time of night or day. Have to work, go to school at night, shop. Life doesn't stop when the sun goes down.
A lot of nurses work 3 pm till 11 pm and do there grocery shopping late.
