Words: vacancy, vacate, vacation, vaccine

Here's a word to the wise,
I know, smart people will listen.

If you see a vacancy sign,
Approach with caution 'n wisdom.
Keep your money deposit,
'Til reading the fine print,
For if you have to vacate,
You're liable to lose rent.

And prior to taking a vacation,
In any faraway land,
Visit a medical doctor,
Stay healthy as you can.
Insist it's fresh vaccine,
He injects in all your shots,
The least your doctor can do,
Is provide the best he's got.
