the icing on the cake
to turn beet red
black sheep of the family
That's not my cup of tea.
a smart cookie
fight like cat and dog
to be tied to his mother's apron strings
My sister and I are like chalk and cheese.
We are birds of a feather.
blood is thicker than water
to be packed like sardines
a smart alec
as cool as a cucumber
My son is the apple of my eye.
