Good things about being alone:
You can have whatever you want for supper.
You don't have to have supper. You can just have wine.
One side of your bed can be covered with books.
The laundry basket only fills up half as fast.
You can take a nap without explaining why you are tired.
No one expects you to be home at any certain time.
If you fall asleep on the couch while watching TV, you can stay there.
