یه شعر زیبا درباره حروف صدادار (Vowels) در انگلیسی

VOWELS

We are little fairy creatures,
All of different voice and features,
One of us in "glass" is set,
One of us is found in "jet".

One in "tin" is well surrounded,
By a "box" the fourth is bounded,
And the fifth, I tell you true,
Never will it fly from "you".

Who, or what, are we?
