Dear Mom and Dad,

     The time has come:I'm graduating, and I thank you both for all your help during these

15 years. I still remember when you used to say, "You can be whatever you want" I'm so

glad you are my parents, especially when I hear kids say they don't get on well with theirs.

I'm glad that you support(支持) me when I decide to do anything. You always try to help,

and that's important to me .

     Dad, I remember when you first took me fishing. I loved going even though I never caught

anything. I also remember when you would get angry with me. I realize you were only trying

to show me the right way. When Iwould cry, you would always be there to try to cheer me

up. That's what I call a good, loving, caring dad. Sometimes you and Mom don't agree with

me, but you are there by my side in anything that I do, and that's why I love you both so much.

     Mom, I enjoy going out with you and having our happy time every Friday night, and I hope

that never changes. I love telling you everything;the best part about you is that you listen. I'm

glad we do a lot together. You love to have fun, and Dad does, too. You always give me your

opinion and I listen.

     Thank you for bringing me up.

                                                                                                        Love always,
