Beat around the bush – avoid the main topic
Best of both worlds – all the advantages
Hit the hay – go to sleep
Kill two birds with one stone – accomplish two things at the same time
Last straw – the final problem to a series of problems
Miss the boat – missed a chance
On the ball – understands the situation well
A piece of cake – simple
Whole nine yards – all of it
Steal someone’s thunder – take credit of something not yours
