I was born in Toledo. The only fire I was ever near was at a neighbors and my brother and I put it out. It was a grease fire! LOL!!!!
As I get older, I forget a lot of things and it's kinda of scarey.
Geeze.....tell me about it! At 52, I look at people I know and think, "What's her name?!" My "thing" is the tea kettle. Hubby got me a whistler and you can't ignore it.
