An excellent opportunity that is not likely to be repeated
Pull one's leg
A golden opportunity
To refuse to move backwards
To kid, fool, or trick someone
Bone of contention
Burst into tears
Within a stone's throw
The subject or point of an argument
Very close to something
Dog in the manger
To begin to cry suddenly
One who prevents others from enjoying something despite having no use for it.
Burn the midnight oil
Hold your ground
To stay up working, especially studying, late at night
