I have always wiggled my feet - when we had kittens I didn't realise how much my feet were moving until they pounced
. Even in the night I am aware that my feet move. Don't know if they move when I'm asleep ……..
I also used to hum under my breath, I remember my Dad telling me off a lot because it annoyed him and disturbed his hobby. He used to bite his tongue when doing close work.
I have ear worms often, usually musical but occasionally phrases ……... A clue in a crossword was 'elephant's name in a childrens' song' - Nellie was going round and round all day
.
Pity habits don't spread to housework
……. but only a little bit
!
