Cup of T

Have some cup of tea, but how could that be;
the first thing you need is put second - its thirst!
That's what you deem. No want makes wanton
and spill your coffee. To have your tea, your cup
must be sizable, but empty. Dare the Truth with me!

Have some cup of tea, but how'd you drink bricks?
If your cup is so full that not even your fist fits in;
how to pour some sour and salty thoughts into you!
How to change your taste, if you seek none indeed;
Is it T or B or C - will it follow my lead or return to led.

Have some cup of tea, and don't opt to snicker
hunger while not being hungry, or thirst while not thirsty.
If you're not blind you don't look for glasses;
If you're not old, you don't look for a cane.
Admit to yourself if there is something you'll need...

Have some cup of tea, perplexed shall not be;
don't expect to find awesome or special in here.
Feel free and enjoy - that's all stuff you'll need!
He who hungers and thirsts shall be fulfilled;
others mayday the rued mayhammered glee...
