My mom used to do that vvhen I vvas a kid... drove me nuts.The nerve of some to interrupt the hibernation.
For a while, I lived next door to a woman that got a ride from her mother to go to work at 5 am. She would park right outside our apartment. Instead of going in, she would lay on the horn. Until the morning my kids were sick and I needed sleep from being up late with them. She didn't like what I had to say.
She never did it at 5am, though.
I vvas glad vvhen she got a cell phone and could just call vvhatever friend's house I vvas at.
