Pretty minor for me in 69 years… Had a bike stolen from the side of my parents house when I was 12. Forgot to lock my car parked on the street in front of my house about 5 years ago and lost a really nice flashlight, a digital tire pressure gauge and an electric tire pump.
I’d bought the tire pump on sale at Canadian Tire, and the next time I was shopping there, a newer and better version was on sale.
