When I was about 4 or 5, I saw a woman on tv who had some quart jars of blood. She said that this was how much blood we had in our bodies. Either she failed to say, or I just missed, that our bodies make new blood. I thought what was in the jars was it - and it better last a lifetime.
So every time I got the smallest cut, I totally freaked. Family just thought I was a sissy for the longest time...
My Dad came in one night and said he was going to make tacos. I said “I want one!”. Was very disappointed when I found out they weren't walki-talkies.
