Lovely Grandpa

Today, I met a very lovely old man at on Italki. He wants to study Chinese and know about our culture. I admire him very much because he thinks it's never too late to study. But Now, I want to tell you something about me. Though I am writing an entry here, I just don't like writing small compositions. I'm not good at this!

(While using "but" to begin a sentence, one should remember that the two sentences connected by it should be referring to the same thing.)

e.g.

He thinks it's never too late to study, but I think, age is an important factor in learning.

He likes to write here often, but I hate writing, especially small compositions.
