To move connections for some
To pull a few strings
Something we are familiar with; a place we know well
Like the back of my hand
To do the same thing that somebody did previously
To follow in someone's footsteps
This is an area or topic that I don't know much about
I am out of my depth
Extremely happy
I am over the moon
Extremely busy?
I am up to my eyes in work
Just in time
In the nick of time
