I live with my grandfather half the time, and drive his car. I’ve carried an extra set of keys ever since I locked myself out of the car years ago. My sister had to drive to my grandfather’s for the extra key, then drive downtown to give it to me. Fortunately, it was a nice day - sunny, but with a nice breeze. Unfortunately, my sister didn’t appreciate the inconvenience to her.
The extra set also has keys to all the doors at my grandfather’s. The door to the garage is usually unlocked, but if the power goes out I won’t be able to open the garage door. If it’s late, my grandfather will be sleeping (without his hearing aids), and even Toto (a little terrier) would have trouble waking him. He keeps all the other doors locked all the time. Unfortunately, I usually have to got to the usually unlighted back door to get in, since the front screen-door has a keyless lock.
I also keep extra change in the car, and I always check all the locks before exiting the car (no automatic locks), and try the driver’s side door handle afterwards. And I’m so used to putting on my seatbelt, that I’ve sometimes put it on when just getting in the car to get something. If I leave something like a portable CD player in the car when I’m out, I always hide it in the glove compartment or under the blanket in the back seat - away from prying eyes.
I don’t have a savings account (unemployed and still paying off student loans that led to nothing) but I do have a small account in which I keep around a hundred bucks in case of emergency. Otherwise, I only carry cash. No credit cards, even if I could get one. And I always keep my wallet in my right front pocket. Safer, more convenient, and more comfortable, IMO.
I frequently clean out my computer’s caches and history, and run programs which scan for unwanted nasties I may have picked up off the internet.
Before letting the dog out at night (on his rope), I always bang the back screen-door to scare away any animals I don’t see that might be near - particularly skunks. (Picked that up from my grandfather.) Toto’s never encountered a skunk yet, but unfortunately rolled around in a spray area once.
For someone who suffers from headaches and migraines, I never remember to bring medication with me when I go out to town or to the movies. Never forget it when I’m going out of town though.
