Lines 11-12 The speaker ends the poem by promising his kid that he will make a commitment. The speaker vows never to "like too much" what he enjoys. In other words, even if he likes something, he won't grow too attached to it because you never know when it will be taken away. Sad. Vowels are sounds made with the voice or the lungs that indicate a promise or agreement. A vowel sound can be short or long. When you say the word "vowel," think of either an "a" or an "o." Vowels play an important role in language acquisition because they help children distinguish words that are used together often such as dog and cat vs. duck and goat. Also, vowels are responsible for differentiating sounds that would otherwise be hard to differentiate such as the English /ə/ (short vowel) and /ɔ/ (long vowel). In this case, the speaker has promised not to grow too attached to his love interest because she could stop calling or texting him at any time. This idea is expressed through the use of the present continuous verb form. Present continuous verbs are those that are used to describe actions being done now. They are formed by adding the present simple form of the verb "to be" followed by the present tense of the main verb: "I am eating." "You are singing beautifully."
