Not long after learning to read, I thought the number next to the town name on road signs was the temperature of that town, not the distance to it. I guess that came from my dad always wanting to see the weather on the news each night. I think I even said one day "look how hot it is in that town" and my parents agreed. I don't think they were being mean, I think they just had no idea what I was on about. I was a little embarrassed (but no one else knew my little secret) when I learned what the numbers really meant.
I also wondered how you were supposed to be able to read those signs with four or more different towns on them, because being a new reader, I could barely read the top one before we passed the sign, and of course everyone read at the same speed as a 4 year old.
