Nostalgic or Lethargic?

I wrote the word "nostalgic" in my last post which made me remember a story from when I was a kid. When I was a kid, I got a lot of words mixed up (this is apparently common to people with attention deficit disorder, like me). Two such words were nostalgic and lethargic. One time when I was about twelve our dog was acting lethargic so I called the vet clinic to ask them whether we should bring them in. When they asked what our dog's symptoms were I said, "well he's been acting very nostalgic for the last couple of days..." There was a long pause, then the technician on the line said, "...do you mean lethargic?" Now when I think back on that, I wonder if the technician might have actually tried to picture a nostalgic dog before figuring out what I meant.

I also used to think for some reason that the word "jaywalking" meant "prostitution" (somehow someone must have confused me because these two words are nothing alike). One time when I was in middle school there was a story in the news about a blind man who got ticketed for jaywalking. Everyone was in a fit because it's not very fair for a blind man to get a ticket, although the police thought the guy should have to follow the law just like everyone else. I completely misinterpreted the story though. I thought the blind man was prostituting, and everyone was in a fit because blind men aren't normally prostitutes. Whenever I volunteered my opinion that this guy should have known he would get a ticket for jaywalking (translation: prostitution) since it is in fact illegal... I got more than a few weird looks.
