Now here’s a strange one that is not computer related, but I’m sure everyone has done this one in their lifetime. I first noticed this trick when I purchased my new car about amount ago. The gas cap of my new car – was on the opposite side of the car that I’m used to, so I constantly dealt with issues of remembering which side the gas cap was on. After getting tired of having to backup at every gas station – I noticed a quick trick that will certainly help you remember which side of the car your gas cap is on.
