Whenever someone copies what I'm doing, I never know whether to use the phrase "copy cat" or "monkey see, monkey do".
I can't find any rules around this issue. Maybe if I'm engaged in simian behaviour, like sitting on a leather sofa smoking a cigar and pondering the future – and someone copies me – I should go with monkeys.
If I'm licking myself, I'll use "copy cat".
If I had a great mind, I would go with "great minds think alike".
I think "fools seldom differ" works better in my case.
