Thankfully I had Simba, the sweetest orange tabby that ever lived. I would fall asleep at night by holding him close to me and getting him to purr. He had a loud motor, and it would drown everything else out. If he would stop, I'd just start petting him a little, and he'd start up again.
I'm much better now that I'm older, and I've been living in the same place for 6 years, so I'm familiar with all of this building's noises.
Here's a funny story about my biggest scare ever... (well, it's funny now, I wasn't very amused at the time).
So I was about to drift off to sleep...
When suddenly there was a very loud noise:
It was the loudest noise I ever heard
and the whole building shook.
I managed to climb out of bed to turn on the light and grab my phone. I called my best friend, despite the fact that it was 1:30 AM.
She tried to talk me down, but I was way too freaked out. She told me to call a Taxi, but I didn't even want to go downstairs.
So she did a three-way to call the Taxi, and I waited for it holding my cordless telephone.
Once I was safely in the cab on my way to her place, we hung up.
One week later, as I was chatting with my neighbor, I casually mentioned the incident, and that's when he told me he had been sliding on his wood floor and slammed right in to a table.
