Head
Say something off the top of your head
Say the first thing that you think of
Put your foot in it
Say the wrong thing and feel embarrassed
Give someone a hand
Help someone
Keep and eye on something
Watch to make sure something is safe
Have a finger in every pie
Be involved in many different activities
Put your head on the block
Take a big risk which may damage your position
Start off on the wrong foot
Make a bad start when meeting someone
Have time on your hands
Have too little to do
Turn a blind eye
Pretend not to see something
Let something slip through your fingers
Miss an opportunity
Keep your head
stay calm and in control
Stand on your own feet
Be independent and not rely on other people
Have a free hand
Be able to make your own decisions
Need eyes in the back of your head
Need to be watching in all directions
Cross your fingers
Hope that everything will work out well
Do something standing on your head
Do something very easily
Get itchy feet
Want to travel or to move on to something new
Live from hand to mouth
Have very little money to live on
Be up to your eyes in something
Be very busy
Have your fingers on the pulse
Know all the latest news and what is happening
Bury your head in the sand
Pretend that something isn't happening
Put your foot down
Assert your authority
Have your hands full
Be very busy
Pull the wool over someone's eye
Deliberately mislead someone
Put your finger on something
