Sometimes it's little things like a lady I worked for always used the phrase, "Like I said." Or the family friend who introduced "horrid" into my vocabulary. Or Rosie's famous "sinner!"
I was randomly thinking of two in the last week or so:
"I have to watch my girlish figure." - my Grandma, used as an explanation for not eating the yummy goodies she had made for us.
"The natives are getting restless." - Another lady I worked for/friend when the kids were cranky/hungry/tired.
A third popped into my head while I've been writing:
"And we have great hair." - a friend I used to work for, used as the end of many conversations.
Any everyday catch phrases you'd care to share?
