My fairy

I have a fairy by my side
Which says I must not
sleep,
When once in pain I loudly cried
It said "You must not weep". -
If, full of mirth, I smile and grin,
It says "You must not laugh";
When once I wished to drink some gin
It said "You must not quaff". -
When once a meal I wished to taste
It said "You must not bite";
When
to the wars I went in haste
It said "You must not fight". -
"What may I
do?" at length I cried,
Tired of the painful task.
The fairy quietly
replied,
And said "You must not ask". -
