Dear Grandpa,
How are you those days? I have been missing you very much after I went to college a year ago. Whenever I think of the old days, I feel very happily. I still remember when I was child, you always held me in your arms and told me stories till I fall asleep. We often went to the fields to enjoy the pleasant view there. You told me the name of different plants and their characteristics. Gradually, I became interesting in biology and chose to learn biology when I entered into the college. Now my friend Ann, together with me, are going to do field study and the findings will be use as materials for our research. Since we’ll do the study in our hometown, I hope to see you by then.
Yours,
Daisy
