Different Strokes For Different Folks(everyone has different interests and tastes)
It's hard to understand how MIllie and Ron ever got together. She has always gone in for sailing and he can't stand to be on water. He enjoys the opera and she likes jazz.
You know what they say; "Different strokes for different folks!"
You don't have to tell me that everyone has different interests and tastes. I still can't figure out what attracted them to each other in the first place.
Haven't you heard that opposites attract?
go in for = like
